| 1 | Enhanced atmospheric phosphorus deposition in Asia and Europe in the past two decades显示文摘磷是植物生长必需的元素,磷缺乏将限制植被生产力及碳汇功能.为厘清全球大气磷沉降的时空格局,本文收集了1959-2020年发表的396条观测资料.结果发现,全球大气磷沉降的几何均值为0.32 kg ha~(-1)yr~(-1),全球大气磷库约4.4 Tg yr~(-1).与1959-2000年相比,近20年亚洲和欧洲大气磷沉降呈现上升趋势,主要来源是农业活动,沙尘传输和燃烧源排放.碳中和背景下,清洁空气行动是否会改变磷沉降的途径和形态,进而影响到生态系统的结构和功能,是需要回答的科学问题. | Yuepeng Pan Bowen Liu Jing Cao Jin Liu Shili Tian Enzai Du | 2021 | Atmospheric and Oceanic Science Letters2021，14，5： | 5 |

| 3 | Revisiting the Concentration Observations and Source Apportionment of Atmospheric Ammonia显示文摘While China’s Air Pollution Prevention and Control Action Plan on particulate matter since 2013 has reduced sulfate significantly,aerosol ammonium nitrate remains high in East China.As the high nitrate abundances are strongly linked with ammonia,reducing ammonia emissions is becoming increasingly important to improve the air quality of China.Although satellite data provide evidence of substantial increases in atmospheric ammonia concentrations over major agricultural regions,long-term surface observation of ammonia concentrations are sparse.In addition,there is still no consensus on whether agricultural or non-agricultural emissions dominate the urban ammonia budget.Identifying the ammonia source by nitrogen isotope helps in designing a mitigation strategy for policymakers,but existing methods have not been well validated.Revisiting the concentration measurements and identifying source apportionment of atmospheric ammonia is thus an essential step towards reducing ammonia emissions. | Yuepeng PAN Mengna GU Yuexin HE Dianming WU Chunyan LIU Linlin SONG Shili TIAN Xuemei LÜ Yang SUN Tao SONG Wendell WWALTERS Xuejun LIU Nicholas AMARTIN Qianqian ZHANG Yunting FANG Valerio FERRACCI Yuesi WANG | 2020 | Advances in Atmospheric Sciences2020，37，9： | 4 |
| 4 | Toward the Enhancement of Critical Performance for Deep-Ultraviolet Frequency-Doubling Crystals Utilizing Covalent Tetrahedra显示文摘Deep-ultraviolet(deep-UV,λ<200 nm)coherent light is emerging as an indispensable driving force behind the innovation of optics and materials science.The deep-UV-driven applications range from laser interference photolithography to precise micromachining to futuristic ideas such as space propulsion using remotely controlled positioning lasers.Unlike conventional approaches to obtaining deep-UV light,for instance,synchrotron radiation,direct laser excitation,and gas discharge,nonlinear frequency conversion can be regarded as a more attractive way to endow such resource with high photon energy,high photon flux,and high spectral resolution.Actually,the nonlinear frequency conversion can be efficient only with the use of highperforming frequency-doubling crystals,which should be well-suited to the physics of nonlinear optical process.However,the necessary prerequisites for a practical frequency-doubling crystal are extremely strict,and thus very few crystals can be used to generate the deep-UV light.Faced with this,sustained effort has been expended by chemists and materials scientists toward discovering novel deep-UV frequency-doubling crystals.Studies have so far indicated that the main difficulty in finding a perfect candidate comes from the combination of three critical properties(absorption edge,nonlinear optical coefficients,and birefringence)into one crystal because they share the mutual relation of restriction and influence.In this Account,we present recent progress in discovering emergent deep-UV frequency-doubling crystals with the discussion of our efforts to balance the three critical properties by introducing the covalent tetrahedra[MO4−nXn](n=1−3),in which M refers to central atoms such as B,P,Si,S,Al,Zn,and Be and X can be apical atoms such as F,Cl,Br,and N.By analyzing the influence of the covalent tetrahedra on optical properties,we came to the conclusion of how to use the oxidized tetrahedra to achieve the improvement of the absorption edge,nonlinear optical coefficients,and birefringence for deep-UV frequency-doubling crystals.The followings are the key points in achieving the above goals:(i)elimination of dangling bonds with covalent tetrahedra to push the absorption edge of crystals into the deep-UV spectral region;(ii)orbital hybridization enhancement,charge-transfer energy reduction,and symmetry breaking of original tetrahedra with the introduction of X atoms and thereby the achievement of the enhancement of nonlinear optical coefficients;and(iii)uniform alignment of tetrahedral distorted units and the introduction of polarized X atoms containing[MO_(4−n)X_(n)]tetrahedra with high polarizability anisotropy to cause the large enhancement of birefringence.These findings allow us to understand the microcosmic behaviors of covalent tetrahedra on pushing the current limitations and provide an optional functional group toward the maximum thresholds of three critical parameters for deep-UV frequency-doubling crystals.Finally,we conclude this Account with a better understanding of the positive roles of covalent tetrahedra in enhancing the optical performance and how they can facilitate the construction of high-performing deep-UV crystals. | Miriding Mutailipu Zhihua Yang Shilie Pan | 2021 | Accounts of Materials Research2021，2，4： | 2 |

| 6 | From borophosphate to fluoroborophosphate:a rational design of fluorine-induced birefringence enhancement显示文摘The introduction of oxofluoride anion into anionic group assists to tune optical properties owing to the change of coordination,electronegativity,and according anionic framework.Here,we proposed a rational design of new compounds by fluorine-driven structure and optical property evolution.A new borophosphate Ba_(2)BP_(3)O_(11)with the monoclinic space group P2_(1/c) has been synthesized in the sealed system.Ba_(2)BP_(3)O_(11)exhibits a rare P-O-P bridge formation,which is the first example in alkaline-earth metal borophosphates.By further substituting[BO_(4)]^(3-)with[BO_(3)F]^(4-),the first alkaline-earth metal/lead fluoroborophosphates M_(2)BP_(2)O_(8)F(M=Ba and Pb)with the same space group were designed.Since the scissors effect of fluorine,in M_(2)BP_(2)O_(8)F(M=Ba and Pb),a BO_(3)F tetrahedron corner-sharing with three PO_(4)tetrahedra forms 1D chains along the b-axial direction,which are filled by MO_(n)(M=Ba/Pb,n=5,6,8)distorted polyhedra.The first principles calculation shows that the borophosphate Ba_(2)BP_(3)O_(11)has a birefringence about 0.013@1,064 nm,while the fluoroborophosphates M_(2)BP_(2)O_(8)F(M=Ba and Pb)have the values of 0.035 and 0.043@1,064 nm,respectively.Such an apparent enhancement in birefringence is derived from synergies of the oxyfluoride and cation.The introduction of fluorine-containing heteroanionic groups provides a feasible strategy to design novel promising optical materials. | Wenyao Zhang Zhizhong Zhang Wenqi Jin Ruonan Zhang Meng Cheng Zhihua Yang Shilie Pan | 2021 | Science China Chemistry2021，64，9： | 1 |

| 11 | Na2ZnSn_2S6:A mixed-metal thiostannate with large second-harmonic generation response activated by penta-tetrahedral [ZnSn4S(14)]^(10-) clusters显示文摘A sodium zinc thiostannate Na_2ZnSn_2S_6 is reported with its interesting structural features and property characteristics. It crystallizes in the polar space %xou^Fddl(No. 43) with the unit cell parameters of a=12.945(3),b=23.556(5), c=7.2774(15)and Z=8. In its structure,Zn-centered penta-tetrahedra [ZnSn_4S_15]^(12-)clusters arrange regularly along the diagonals of ab and ac planes to form a 3D tunnel structure with charge-balanced Na^+ cations located inside the tunnels. Note that SnS_4 tetrahedra connect with each other by sharing comers to form infinite _∞[SnS_3]_n? chains that are rarely found in known alkali-thiostannates_Remarkably,Na_2ZnSn_2S_6 exhibits the good NLO performances,such as large SHG response(4 times that of AgGaS_2 at55-88 um under the 2.09 um radiation), wide infrared(IR) transmission region(0.35-25 um) and relatively high laser damage threshold(77.5 MW/cm^2, ~2 times that of AgGaS_2). Theoretical calculations have also been performed to investigate the structure-property relationship and the results indicate that the origin of NLO effect can be attributed to the penta-tetrahedra[ZnSn_4]^(12-) clusters. | LI GuangMao WU Kui LIU Qiong YANG ZhiHua PAN ShiLie | 2017 | Science China(Technological Sciences)2017，60，10： | 1 |

| 13 | Ba_(2)B_(9)O_(13)F_(4)·BF_(4):first fluorooxoborate with unprecedented infinite [B_(18)O_(26)F_(8)] tubes and deep-ultraviolet cutoff edge显示文摘Fluorooxoborate has emerged as a promising system for exploring optical materials due to their rich structural chemistry and physicochemical properties,yet so far not fully studied.Herein,we report a new fluorooxoborate,Ba_(2)B_(9)O_(13)F_(4)·BF_(4),which contains the greatest variety of structural basic units,[BO_(3)],[BO_(2)F_(2)],[BO_(3)F],and[BF_(4)],and exhibits unprecedented 1D infinite[B_(18)O_(26)F_(8)]tubes.The unique structure avoids the dangling bonds caused by terminal oxygens,which is beneficial to the large bandgap and deep-ultraviolet cutoff edge.This article expands the crystal structure of fluorooxoborates and contributes to the exploration of deep-ultraviolet optical materials in fluorooxoborate systems. | Huan Pei Xuefei Wang Jie Zhang Fangfang Zhang Zhihua Yang Shilie Pan | 2023 | Science China Chemistry2023，66，4： | 0 |
| 14 | Clamping effect driven design and fabrication of new infrared birefringent materials with large optical anisotropy显示文摘Infrared(IR)birefringent materials with large optical anisotropy and wide transparency range are important for efficient light manipulation in various IR optical devices.Herein,two new IR birefringent materials AMgGeSe_(3)(A=Li,Na)with large optical anisotropy were rationally designed by a rigid octahedron and flexible dimer combined strategy and fabricated in experiment.The introduction of rigid[LiSe_(6)]/[NaSe_(6)]and[MgSe_(6)]octahedra effectively regulates the geometry and arrangement of the flexible[Ge2Se6]dimers,resulting in the birefringence as large as 0.334@1,064 nm in LiMgGeSe_(3) and 0.445@1,064 nm(the largest one in the reported[Ge_(2)Se_(6)]dimer-contained selenides)in NaMgGeSe_(3).Density functional theory(DFT)calculations and statistical analyses highlight the influence of polarizability anisotropy,density,arrangement of units,as well as layer distance on birefringence.The results indicate that AMgGeSe_(3)(A=Li,Na)crystals are the promising IR birefringent materials and it gives an insight into the exploration of new IR birefringent materials with large birefringence based on the clamping effect from rigid groups. | Linan Wang Chenchen Tu Hongbo Gao Jiazheng Zhou Hongshan Wang Zhihua Yang Shilie Pan Junjie Li | 2023 | Science China Chemistry2023，66，4： | 0 |
| 15 | An excellent deep-ultraviolet birefringent material based on[BO2]∞ infinite chains显示文摘Birefringent materials play indispensable roles in modulating the polarization of light and are vital in the laser science and technology.Currently,the design of birefringent materials operating in the deep-ultraviolet region(DUV,λ≤200 nm)is still a great challenge.In this work,we developed a new DUV birefringent crystal LiBO_(2) based on[BO2]∞infinite chains in the Li-B-O system,which simultaneously achieves the shortest UV cutoff edge(164 nm)and the largest birefringence(≥0.168 at 266 nm)among all the reported borate-based DUV birefringent materials.Single crystals of LiBO_(2) with dimensions up to Ø55×34 mm^(3) were grown by the Czochralski method,providing access to large-sized single crystal with low cost.Moreover,it has a high laser damage threshold and stable physicochemical properties.These outstanding characters unambiguously support that LiBO_(2) can be an excellent birefringent material for DUV application. | FANGFANG ZHANG XINGLONG CHEN MIN ZHANG WENQI JIN SHUJUAN HAN ZHIHUA YANG SHILIE PAN | 2022 | Light(Science & Applications)2022，11，9： | 0 |
| 16 | New opportunities for ferroelectric deep-UV nonlinear optical crystals显示文摘Deep-ultraviolet(deep-UV)light with the wavelength below200 nm is one of the most crucial elements of both laser-driven industrial and scientific applications in recent years[1].DeepUV light has been produced using a variety of techniques,such as gas discharge lamps,synchrotron radiation,excimer lasers,free electron lasers,and nonlinear frequency conversion. | Miriding Mutailipu Shilie Pan | 2024 | Science China Materials2024，67，3： | 0 |
| 17 | A Cation-Driven Approach toward Deep-Ultraviolet Nonlinear Optical Materials显示文摘The design of new materials with special performances is still a great challenge,especially for the deep-ultraviolet nonlinear optical materials in which it is difficult to balance large bandgaps and strong second harmonic generation responses due to their inverse relationship.Cation variation not only influences the whole structure frameworks but also directly participates in the formation of electronic structures,both of which could lead to the uncontrollability of the properties of the designed materials.Here,a novel approach,aiming at purposeful and foreseeable material designs,is proposed to characterize the role of cations.By the verification of several series of borates,the influences of cation variation on property changes are explored systematically.Accordingly,a feasible strategy of designing deep-ultraviolet nonlinear optical materials by substituting barium for lead has been concluded,which could obviously blue-shift the ultraviolet cutoff edge and maintain the relatively strong second harmonic generation response(more than 2 times of KH2PO4),achieving the property optimization,and especially works efficiently in fluorooxoborates.The property optimization design strategy and the cation characterization method are not only helpful in exploring nonlinear optical materials but also enlightening in material design and selection. | Cong Hu Meng Cheng Wenqi Jin Jian Han Zhihua Yang Shilie Pan | 2023 | Research2023，，3： | 0 |
| 18 | Rb_(5)Ba_(2)(B_(10)O_(17))_(2)(BO_(2)):The formation of unusual functional [BO_(2)]^(-) in borates with deep-ultraviolet transmission window显示文摘The design and synthesis of new deep-ultraviolet(DUV)optical materials are important but challenging.It is well known that the polarizability anisotropy of linear[BO_(2)]^(−)is larger than those of[BO_(3)]^(3−)and[BO_(4)]^(5−),which is the better choice for exploring excellent optical materials.Here,we search for such crystals in borate systems based on the unusual fundamental structural unit[BO_(2)]^(−).By combining the linear[BO_(2)]^(−)with the traditional triangular[BO_(3)]^(3−)and tetrahedral[BO_(4)]^(5−)units,a new mixed metal borate,Rb_(5)Ba_(2)(B_(10)O_(17))_(2)(BO_(2))was obtained via high-temperature solution method.It exhibits excellent optical properties including a DUV transmission window(188 nm)and suitable birefringence(0.06).It also has good thermal stability and its crystal plates can be prepared easily.Furthermore,the strategies of designing borates with[BO_(2)]^(−)units have been proposed from the transformation of crystal framework and the preparation method. | Yanhui Zhang Fuming Li Rong Yang Yun Yang Fangfang Zhang Zhihua Yang Shilie Pan | 2022 | Science China Chemistry2022，65，4： | 0 |
| 19 | (NH_(4))_(3)B_(11)PO_(19)F_(3):a deep-UV nonlinear optical crystal with unique[B_(5)PO_(10)F]_(∞)layers显示文摘Deep-ultraviolet(DUV)nonlinear optical(NLO)crystals that can extend the output range of coherent light below 200 nm are pivotal materials for solid-state lasers.To date,KBe_(2)BO_(3)F_(2)(KBBF)is the only usable crystal that can generate DUV coherent light by direct second harmonic generation(SHG),but the layered growth habit and toxic ingredients limit its application.Herein,we report a new fluoroborophosphate,(NH_(4))_(3)B_(11)PO_(19)F_(3)(ABPF),containing four different functional units:[BO_(3)],[BO_(4)],[BO_(3)F]and[PO_(4)].ABPF exhibits a KBBF-like structure while eliminating the limitations of KBBF crystal.The unique[B_(5)PO_(10)F]_(∞)layers enhance ABPF’s performance;for example,it has a large SHG response(1.2×KDP)and a sufficient birefringence(0.088 at 1064 nm)that enables the shortest phase-matching wavelength to reach the DUV region.Meanwhile,the introduction of strong B-O-P covalent bonds decreases the layered growth habit.These findings will enrich the structural chemistry of fluoroborophosphate and contribute to the discovery of more excellent DUV NLO crystals. | Bingliang Cheng Zijian Li Yu Chu Abudukadi Tudi Miriding Mutailipu Fangfang Zhang Zhihua Yang Shilie Pan | 2022 | National Science Review2022，9，8： | 0 |
