| 1 | Tunable luminescent CsPb_2Br_5 nanoplatelets:applications in light-emitting diodes and photodetectors显示文摘Unlike organic–inorganic hybrid perovskites, all-inorganic cesium lead halide perovskites hold great promise for developing high-performance optoelectronic devices, owing to their improved stability. Herein, we investigate the perovskite-related CsPb_2 Br_5 nanoplatelets(NPLs) with tunable emission wavelengths via changing the reaction temperatures to 100°C, 120°C, and 140°C. Reaction temperature plays a key role in determining the shapes and thicknesses of the resulting CsPb_2 Br_5 NPLs. A higher temperature is in favor of the formation of smaller and thicker NPLs. To develop their potential applications in optoelectronic devices, green light emitting diodes(LEDs) and photodetectors based on CsPb_2 Br_5 NPLs are fabricated. The green LEDs based on CsPb_2 Br_5 NPLs synthesized at 140°C exhibit an excellent pure green emission(full width at half-maximum of <20 nm) and display a luminous efficiency of 34.49 lm∕W under an operation current of 10 m A. Moreover, the photodetector based on CsPb_2 Br_5 NPLs synthesized at 100°C has better performance with a rise time of 0.426 s, a decay time of0.422 s, and a ratio of the current(with and without irradiation) of 364%. | CENG HAN CUNLONG LI ZHIGANG ZANG MING WANG KUAN SUN XIAOSHENG TANG JIHE DU | 2017 | Photonics Research2017，5，5： | 4 |

| 3 | Inorganic lead-free cesium copper chlorine nanocrystal for highly efficient and stable warm white light-emitting diodes显示文摘Inorganic cesium lead halide(CsPbX_(3), X=Cl, Br, I) nanocrystals(NCs) attract extensive attention because of their excellent optoelectronic performance. However, the classic CsPbX_(3) NCs suffer from toxicity and instability, which impede their further applications in commercial fields. Here the inorganic lead-free cesium copper chlorine NCs are synthesized by a facile hot-injection method. The blue-emission 3D CsCu_(2)Cl_(3) and green-emission 0DCs_(3)Cu_(2)Cl_(5) NCs are prepared at 70℃ and 120℃, respectively, suggesting that the reaction temperature may account for the final components. Owing to the self-trapped exciton effect, the unique optical properties, such as high photoluminescence(PL) quantum yield, broadband emission, large Stokes shift, and long PL decay time, are demonstrated for both cesium copper chlorine NCs. Moreover, highly efficient and stable warm white light-emitting diodes are fabricated with CsCu_(2)Cl_(3) and Cs_(3)Cu_(2)Cl_(5) NCs. The study highlights the promising potential for lead-free cesium copper chlorine nanocrystals in nontoxic solid-state lighting applications. | SHUANGYI ZHAO QIONGHUA MO WENSI CAI HUAXIN WANG ZHIGANG ZANG | 2021 | Photonics Research2021，9，2： | 3 |
| 4 | Ultrapure and highly efficient green light emitting devices based on ligand-modified CsPbBr3 quantum dots显示文摘All inorganic Cs PbBr3 perovskite quantum dots(QDs)have been recognized as promising optical materials tfabricate green light emission devices because of their excellent optical performance.However,regular Cs Pb BrQDs with an oleic acid(OA)ligand show poor stability,which limits their practical application.We replaced thOA ligand in Cs PbBr3 QDs with a 2-hexyldecanoic acid(DA)ligand and,in the synthesis,found that the nematerial has better optical properties than regular Cs PbBr3 QDs(Cs PbBr3-OA QDs).Due to the strong bindinenergy between the DA ligand and QDs,the ligand-modified Cs PbBr3 QDs(Cs PbBr3-DA QDs)show a higphotoluminescence quantum yield(PLQY)of 96%,while the PLQY of Cs PbBr3-OA QDs is 84%.Subsequentlythe Cs PbBr3 QDs coated on the blue light-emitting diode(LED)chips as green phosphors are demonstrated.Thcolor conversion from blue to pure green is achieved by adding the Cs PbBr3-OA QDs solution up to 60μL,whilthe pure green emission devices only need 18μL Cs PbBr3-DA QDs solution under the same concentration.Thultrapure,highly efficient green light-emitting devices based on Cs PbBr3-DA QDs exhibit a luminous efficiencof 43.6 lm/W with a CIE(0.2086,0.7635)under a 15.3 m A driving current.In addition,the green emissiowavelength of the devices based on Cs PbBr3-DA QDs almost has no shift,even under a high injection currenThese results highlight the promise of DA ligand-modified Cs PbBr3 QDs for light-emitting devices and enrich thapplication field of ligand-modified Cs PbBr3 QDs. | Dongdong Yan Shuangyi Zhao Huaxin Wang Zhigang Zang | 2020 | Photonics Research2020，8，7： | 3 |
| 5 | A high-performance bio-tissue imaging method using air flow-assisted desorption electrospray ionization coupled with a high-resolution mass spectrometer显示文摘Mass spectrometry imaging (MSI) technology can simultaneously obtain the spatial distribution of thousands of chemical compounds and has unique advantages compared to other techniques that allow mapping the surface of bio-tissue. Here, we combined an air flow-assisted desorption electrospray ionization (AFADESI) MSI device with a high-resolution mass spectrometer to optimize the system parameters and achieve more accurate spatial distribution characteristics for compounds of interest while investigating bio-tissue sections. The platform set-up, required instrumentation, sample pretreatment, parameter optimization and bio-tissue characterization are described and discussed.Finally, the parameter conditions that can provide optimal ionic intensity and enhanced resolution were confirmed. The reasonable resolution and sensitivity improvements of AFADESI-MSI have been achieved through tandem a high-resolution mass spectrometer system, therefore, it would be a promising technique for the bio-tissue imaging analysis. | Yiwei Lv Tiegang Li Chengan Guo Chenglong Sun Fei Tang Luojiao Huang Zhigang Luo Xin Li Ruiping Zhang Qingce Zang Jiuming He Zeper AbliZ | 2019 | Chinese Chemical Letters2019，30，2： | 2 |
| 6 | Anti-Phase Relationship Between the East Asian Winter Monsoon and Summer Monsoon During the Holocene?显示文摘The relationship between the East Asian winter monsoon(EAWM) and East Asian summer monsoon(EASM) during the Holocene is complicated and remains controversial.In this study,analysis of grain size and benthic foraminiferal oxygen isotope,as well as accelerator mass spectrometry ^(14)C dating was performed on a sediment core retrieved from the newly revealed muddy deposit on the northern South China Sea continental shelf.The history of the EAWM and EASM were reconstructed for the last 8200 a BP.Further analysis in conjunction with previously published paleo-climate proxies revealed that the relationship between the EAWM and EASM during the Holocene is more complex than a simple and strict anti-phase one-both negative and positive correlations were identified.The EAWM and EASM are negatively correlated around 7500,4800,4200,3200,and 300 a BP(cooling periods),while positively correlated around 7100,3700,and 2100 a BP(warm periods).In particular,both the EAWM and EASM intensified during the three positive correlation periods.However,we also found that the relationship between these two sub-monsoons is anti-phase during the final phase of particularly hot periods like Holocene Optimum and Medieval warm period.The possible impact from variations of solar irradiance on the relationship between the EAWM and EASM was also discussed. | GE Qian XUE Zuo YAO Zhigang ZANG Zhengchen CHU Fengyou | 2017 | Journal of Ocean University of China2017，16，2： | 2 |
| 7 | Simultaneous passivation of bulk and interface defects through synergistic effect of anion and cation toward efficient and stable planar perovskite solar cells显示文摘Bulk and interface carrier nonradiative recombination losses impede the further improvement of power conversion efficiency(PCE)and stability of perovskite solar cells(PSCs).It is highly necessary to develop multifunctional strategy to minimize surface and interface nonradiative recombination losses.Herein,we report a bulk and interface defect passivation strategy via the synergistic effect of anions and cations,where multifunctional potassium sulphate(K_(2)SO_(4))is incorporated at SnO_(2)/perovskite interface.We find that K^(+)ions in K_(2)SO_(4)diffuse into perovskite layer and suppress the formation of bulk defects in perovskite films,and the SO_(4)^(2-)ions remain located at interface via the strong chemical interaction with SnO_(2)layer and perovskite layer,respectively.Through this synergistic modification strategy,effective defect passivation and improved energy band alignment are achieved simultaneously.These beneficial effects are translated into an efficiency increase from 19.45%to 21.18%with a low voltage deficit of0.53 V mainly as a result of boosted open-circuit voltage(V_(oc))after K_(2)SO_(4)modification.In addition,the K_(2)SO_(4)modification contributes to ameliorated stability.The present work provides a route to minimize bulk and interface nonradiative recombination losses for the simultaneous realization of PCE and stability enhancement by rational anion and cation synergistic engineering. | Cong Zhang Huaxin Wang Haiyun Li Qixin Zhuang Cheng Gong Xiaofei Hu Wensi Cai Shuangyi Zhao Jiangzhao Chen Zhigang Zang | 2021 | Journal of Energy Chemistry2021，30，12： | 2 |
| 8 | Room temperature synthesis of stable silica-coated CsPbBr3 quantum dots for amplified spontaneous emission显示文摘All-inorganic cesium lead bromide(CsPbBr;)perovskite quantum dots(QDs)with excellent optical properties have been regarded as good gain materials for amplified spontancous cmission(ASE).However,the poor stability as the results of the high sensitivity to heat and moisture limits their further applications.Here,we report a facile one-pot approach to synthesize CsPbBr,@SiO,QDs at room tcmperature.Duc to the effective defects passivation using SiO2,as-prepared CsPbBr,@SiO;QDs present an enhanced photolumincscence quantum yicld(PLQY)and chemical stability.The PLQy of CsPbBr,@SiO,QDs reaches 71.6%which is higher than 46%in pure CsPbBr,QDs.The PL intensity of CsPbBr;@SiO,QDs maintains 84%while remaining 24%in pure CsPbBr3 after 80 min heating at 60℃.The ASE performance of the films is also studied under a two-photon-pumped laser.Compared with the films using pure CsPbBr;QDs,those with as-prepared CsPbBr3@SiO2 QDs exhibit a reduced threshold of ASE.The work suggests that room-temperature-synthesized SiO2-coated perovskites QDs are promising candidates for lascr devices. | QIONGHUA MO TONGCHAO SHI WENSI CAI SHUANGYI ZHAO DONGDONG YAN JUAN DU ZHIGANG ZANG | 2020 | Photonics Research2020，8，10： | 2 |
| 9 | Highly efficient emission and high-CRI warm white light-emitting diodes from ligand-modified CsPbBr_(3) quantum dots显示文摘All-inorganic CsPbBr_(3) perovskite quantum dots(QDs)have received great attention in white light emission because of their outstanding properties.However,their practical application is hindered by poor stability.Herein,we propose a simple strategy to synthesize excellent stability and efficient emission of CsPbBr_(3) QDs by using 2-hexyldecanoic acid(DA)as a ligand to replace the regular oleic acid(OA)ligand.Thanks to the strong binding energy between DA ligand and QDs,the modified QDs not only show a high photoluminescence quantum yield(PLQY)of 96%but also exhibit high stability against ethanol and water.Thereby warm white light-emitting diodes(WLEDs)are constructed by combining lig-and modified CsPbBr_(3) QDs with red AgInZnS QDs on blue emitting InGaN chips,exhibiting a color rendering index of 93,a power efficiency of 64.8 lm/W,a CIE coordinate of(0.44,0.42)and correlated color temperature value of 3018 K.In ad-dition,WLEDs based on ligand modified CsPbBr_(3) QDs also exhibit better thermal performance than that of WLEDs based on the regular CsPbBr_(3) QDs.The combination of improved efficiency and better thermal stability with high color quality indicates that the modified CsPbBr_(3) QDs are ideal for WLEDs application. | Dongdong Yan Shuangyi Zhao Yubo Zhang Huaxin Wang Zhigang Zang | 2022 | Opto-Electronic Advances2022，5，1： | 2 |
| 10 | Bottom-up holistic carrier management strategy induced synergistically by multiple chemical bonds to minimize energy losses for efficient and stable perovskite solar cells显示文摘The defects from electron transport layer,perovskite layer and their interface would result in carrier nonradiative recombination losses.Poor buried interfacial contact is detrimental to charge extraction and device stability.Here,we report a bottom-up holistic carrier management strategy induced synergistically by multiple chemical bonds to minimize bulk and interfacial energy losses for high-performance perovskite photovoltaics.4-trifluoromethyl-benzamidine hydrochloride(TBHCl)containing–CF_(3),amidine cation and Cl^(-)is in advance incorporated into SnO_(2)colloid solution to realize bottom-up modification.The synergistic effect of multiple functional groups and multiple-bond-induced chemical interaction are revealed theoretically and experimentally.F and Cl^(-)can passivate oxygen vacancy and/or undercoordinated Sn^(4+)defects by coordinating with Sn^(4+).The F can suppress cation migration and modulate crystallization via hydrogen bond with FA^(+),and can passivate lead defects by coordinating with Pb^(2+).The–NH_(2)–C=NH^(+)_(2)and Cl^(-)can passivate cation and anion vacancy defects through ionic bonds with perovskites,respectively.Through TBHCl modification,the suppression of agglomeration of SnO_(2)nanoparticles,bulk and interfacial defect passivation,and release of tensile strains of perovskite films are demonstrated,which resulted in a PCE enhancement from 21.28%to 23.40%and improved stability.With post-treatment,the efficiency is further improved to 23.63%. | Baibai Liu Ru Li Qixin Zhuang Xuemeng Yu Shaokuan Gong Dongmei He Qian Zhou Hua Yang Xihan Chen Shirong Lu Zong-Xiang Xu Zhigang Zang Jiangzhao Chen | 2023 | Journal of Energy Chemistry2023，，1： | 1 |

| 12 | Numerical modeling of the seasonal circulation in the coastal ocean of the Northern South China Sea显示文摘The Finite Volume Community Ocean Model(FVCOM)was adapted to the Northern South China Sea(NSCS)to investigate the seasonality of coastal circulation,as well as along-shelf and cross-shelf transport.In fall and winter,southwestward current dominates the NSCS shelf,while the currenfs direction shifts to northeast in summer.The circulation pattern in spring is more complicated:both southwestward and northeastward currents are detected on the NSCS shelf.The mean shelf circulation pattern in winter does not show the permanent counter-wind South China Sea Warm Current(SCSWC)along the 100-200 m isobaths.Meanwhile,the model results indicate a northeastward current flowing along 50-100 m isobaths in spring.Southwestward along-shelf transport varies from 0.30-1.93 Sv in fall and winter,and it redirects to northeast in summer ranging jfrom 0.44—1.09 Sv.Onshore transport is mainly through the shelf break segment southeast of the Pearl River Estuary. | Yang DING Zhigang YAO Lingling ZHOU Min BAO Zhengchen ZANG | 2020 | Frontiers of Earth Science2020，14，1： | 1 |

| 15 | Inorganic halide perovskites for lighting and visible light communication显示文摘Inorganic halide perovskites(IHPs) have received substantial attention due to their unique optoelectronic properties. Among all the intriguing performance, the efficient luminescence of IHPs enables the practical application of white light-emitting diodes(WLEDs) for lighting. During the last decade, IHP-based white lighting sources with a high luminesce and a broad color gamut have been developed as strong competitors to conventional and classic WLEDs based on rare-earth phosphors and blue LED chips. Thus, it inspires us to give an overview of the emerging progress of IHP WLEDs that can function as lighting sources. Here, in this review, the generation of luminescent properties and white light in IHPs are first presented. Then, both photoluminescence and electroluminescence WLEDs with IHPs emitters, including both lead-based and lead-free IHPs, are synthetically discussed to exhibit their advantages. Furthermore, the efforts on the optical performance enhancement of IHPs in WLEDs are demonstrated and summarized. Apart from WLEDs, visible light communication based on IHPs featuring efficient luminescence is proposed to highlight their promising potential in lighting communication.Finally, some perspectives on the evolution and challenges are described, followed by an inspirational outlook on their future development. | Shuangyi ZHAO Qionghua Mo Baiqian Wang Wensi Cai Ru Li Zhigang Zang | 2022 | Photonics Research2022，10，4： | 1 |
| 16 | Performance enhancement of solution-processed InZnO thin-film transistors by Al doping and surface passivation显示文摘Solution-processed oxide semiconductors have been considered as a potential alternative to vacuum-based ones in printable electronics.However,despite spincoated InZnO(IZO)thin-film transistors(TFTs)have shown a relatively high mobil-ity,the lack of carrier suppressor and the high sensitivity to oxygen and water molecules in ambient air make them potentially suffer issues of poor stability.In this work,Al is used as the third cation doping element to study the effects on the electrical,optoelectronic,and physical properties of IZO TFTs.A hydrophobic self-assembled monolayer called octadecyltrimethoxysilane is introduced as the surface passivation layer,aiming to reduce the effects from air and understand the importance of top surface conditions in solution-processed,ultra-thin oxide TFTs.Owing to the reduced trap states within the film and at the top surface enabled by the doping and passivation,the optimized TFTs show an increased current on/off ratio,a reduced drain current hysteresis,and a significantly enhanced bias stress stability,compared with the untreated ones.By combining with high-capacitance AlO_(x),TFTs with a low operating voltage of 1.5 V,a current on/off ratio of>10^(4) and a mobility of 4.6 cm^(2)/(V·s)are demonstrated,suggesting the promising features for future low-cost,low-power electronics. | Wensi Cai Haiyun Li Mengchao Li Zhigang Zang | 2022 | Journal of Semiconductors2022，43，3： | 0 |
| 17 | Ionic liquids in perovskite solar cells显示文摘Metal halide perovskites have gained a lot of attention particularly in recent years due to their excellent optoelectronic properties and simple scalable processability[1−3].One major application of halide perovskites is solar cells,however,despite the power conversion efficiencies(PCEs)have already reached around 25%[4,5],the long-term stability issue of such devices still impedes their commercialization. | Wensi Cai Zhigang Zang Liming Ding | 2021 | Journal of Semiconductors2021，42，8： | 0 |
| 18 | High-performance CsPbBr_(3)@Cs_(4)PbBr_(6)/SiO_(2) nanocrystals via double coating layers for white light emission and visible light communication显示文摘Owing to their outstanding optoelectronic properties,all-inorganic CsPbBr_(3) perovskite nanocrystals(NCs)are regarded as excellent materials for various optoelectronic applications.Unfortunately,their practical applications are limited by poor stability against water,heat,and polar solvents.Here,we propose a facile synthesis strategy for CsPbBr_(3)@Cs_(4)PbBr_(6) NCs via tetraoctylammonium bromide ligand induction at room temperature.The resulting CsPbBr_(3)@Cs_(4)PbBr_(6) NCs show a high photoluminescence quantum yield of 94%.In order to prevent Cs4PbBr6 from being converted back to CsPbBr_(3) NCs when exposed to water,a second coating layer of SiO2 is formed on the surface of the CsPbBr_(3)@Cs_(4)PbBr_(6) NCs by the facile hydrolysis of tetramethoxysilane.The resulting CsPbBr_(3)@Cs_(4)PbBr_(6)/SiO_(2) NCs with their double coating structure have outstanding stability against not only a polar solvent(ethanol)but also water and heat.The as-prepared CsPbBr_(3)@Cs_(4)PbBr_(6)/SiO_(2) NCs serve as green emitters in efficient white light-emitting diodes(WLEDs)with a high color rendering index(CRI)of 91 and a high power efficiency 59.87 lm W−1.Furthermore,the use of these WLEDs in visible light communication(VLC)results in a maximum rate of 44.53 Mbps,suggesting the great potential of the reported methods and materials for solid-state illumination and VLC. | Xianwen Li Wen Ma Dehai Liang Wensi Cai Shuangyi Zhao Zhigang Zang | 2022 | eScience2022，2，6： | 0 |
| 19 | Ion diffusion-induced double layer doping toward stable and efficient perovskite solar cells显示文摘The perovskite layer,electron transport layer(ETL)and their interface are closely associated with carrier transport and extraction,which possess a pronounced effect on current density.Consequently,the dissatisfactory electric properties of functional layers pose a serious challenge for maximizing the thermodynamic potential of current density of perovskite solar cells(PSCs).Herein,we report an ion diffusion-induced double layer doping strategy for efficient and stable PSCs,where LiOH is directly added into SnO_(2)colloidal dispersion solution.It is uncovered that a small amount of Li+ions remain in the ETL and doped SnO2 while a large amount of Li+ions diffuse to SnO_(2)/perovskite interface and into perovskite layer and gradient concentration distribution is spontaneously formed.The Li+ion doping endows both perovskite and SnO_(2)layers improved electric properties,which contributes to facilitated carrier transport and extraction.Moreover,the crystallinity and grain size of perovskite films are enhanced after doping.The doped device delivers a higher power conversion efficiency(PCE)of 21.31%together with improved ambient stability in comparison with the control device(PCE=19.26%).This work demonstrates a simple and effective ion diffusion-induced double layer by chemical doping strategy to advance the development of perovskite photovoltaics. | Qixin Zhuang Huaxin Wang Cong Zhang Cheng Gong Haiyun Li Jiangzhao Chen Zhigang Zang | 2022 | Nano Research2022，15，6： | 0 |
| 20 | Stable yellow light emission from lead-free copper halides single crystals for visible light communication显示文摘Yellow light-emitting diodes(LEDs) as soft light have attracted abundant attention in lithography room, museum and art gallery. However, the development of efficient yellow LEDs lags behind green and blue LEDs, and the available perovskites yellow LEDs suffer from the instability. Herein, a pressure-assisted cooling method is proposed to grow lead-free CsCu2I3single crystals, which possess uniform surface morphology and enhanced photoluminescence quantum yield(PLQY) stability, with only 10% PLQY losses after being stored in air after 5000 h.Then, the single crystals used for yellow LEDs without encapsulation exhibit a decent Correlated Color Temperature(CCT) of 4290 K, a Commission Internationale de l’Eclairage(CIE) coordinate of(0.38, 0.41), and an excellent 570-h operating stability under heating temperature of 100°C. Finally, the yellow LEDs facilitate the application in wireless visible light communication(VLC), which show a-3 dB bandwidth of 21.5 MHz and a high achievable data rate of 219.2 Mbps by using orthogonal frequency division multiplexing(OFDM) modulation with adaptive bit loading. The present work not only promotes the development of lead-free single crystals, but also inspires the potential of CsCu2I3in the field of yellow illumination and wireless VLC. | Baiqian Wang Yuru Tang Xin Yang Wensi Cai Ru Li Wen Ma Shuangyi Zhao Chen Chen Zhigang Zang | 2023 | Nano Materials Science2023，5，1： | 0 |
