| 3 | Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility. | Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He | 2016 | Matter and Radiation at Extremes2016,1,1: | 2 |
| 4 | The effect of hydrogen-bond in alcoholic solvent on the solvation ultrafast dynamics of oxazine 750 dye显示文摘The ultrafast dynamics of oxazine 750 dye was studied in methanol,ethanol,1-propanol,1-butanol solvents using the femtosecond time-resolved stimulated emission pumping fluorescence depletion (FS TR SEP FD) technique. The faster decays on the hundreds of femtosecond time scale and the slower decays on the order of picosecond were found. The intramolecular vibrational redistribution (IVR) and the solute-solvent intermolecular photoinduced electron transfer (ET) should account for the faster decay,while the slower decay is attributable to the diffusive solvent relaxation. The results show that the intermolecular hydrogen-bonding network will hinder the rearrangement of the alcoholic molecules in the solvation process and the time constants of the slower diffusive solvent relaxation decays are found to increase with the hydrogen-bonding energy in alcoholic solvents. | ZHOU LiChuan SHI Ying LIU JianYong HAN KeLi | 2008 | Chinese Science Bulletin2008,53,13: | 2 |
| 5 | Bismuth doped lead-free two-dimensional tin based halide perovskite single crystals显示文摘Heterovalent-metal doping is an efficient tool to tune the optoelectronic properties of the famous halide perovskites.Previous studies have focused on the heterovalent-doping in three-dimensional(3D) halide perovskites.However, there is a lack of such doping in two-dimensional perovskites which possess unique optoelectronic properties and improved chemical stability as compared to 3D analogues.Here, we present successful doping of Bismuth into the lattice of lead-free, two-dimensional perovskite PEA2SnBr4 single crystals.Structural characterizations demonstrate that the doped crystals possess identical crystal structure and layered morphology with the pristine one.Intriguingly, we find the PL peak and spectral shape can be tailored by tuning the concentration of Bi dopants.Femtosecond transient absorption spectroscopy is performed to understand the underlying mechanism related to tunable PL behaviors, and a clear picture of the Bismuth-doping impact is provided. | Ruiling Zhang Xin Mao Pengfei Cheng Yang Yang Songqiu Yang Tuerdi Wumaier Weiqiao Deng Keli Han | 2019 | Journal of Energy Chemistry2019,28,9: | 2 |
| 6 | Rational design of a visible-light photochromic diarylethene:a simple strategy by extending conjugation with electron donating groups显示文摘Photochromic diarylethenes have been widely used in many fields. However, their cyclization process must be induced by UV light. In this article, a simple strategy is developed by extending π-conjugation with electron donating groups. The modified dirylethene derivative can photocyclolize under 405-nm light with a good photochromic efficiency. Meanwhile, its absorption and moderate fluorescence can be switched effectively in both directions by visible lights(405 and 520 nm, respectively) in different solutions and in living cells. We believe that this simple method will become a versatile strategy for developing various dirylethylenes with visible-light photochromism. | Shanliang Tang Fengling Song Meiheng Lu Keli Han Xiaojun Peng | 2019 | Science China Chemistry2019,62,4: | 2 |
| 7 | Doped all-inorganic cesium zirconium halide perovskites with high-efficiency and tunable emission显示文摘Doping enables manipulation of both the electrical and optical properties of halide perovskites.Herein,we incorporated Te^(4+) into Cs_(2)ZrCl_(6) single crystal,simultaneously preserving the vacancy-ordered structure,to obtain an efficient yellow-emitting perovskite with a near-unity photoluminescence quantum yield(PLQY≈97.6%).Te^(4+) doping modifies the hue and emission color of pristine Cs_(2)ZrCl_(6),generates new absorption channels,and successfully extends the excitation energy from<280 nm to 360-450 nm range.Detailed spectral characterizations,including ultrafast femtosecond transient absorption measurements,reveal that the bright yellow light is derived from triplet self-trapped excitons.Moreover,further tuning doping concentration enables Te-doped Cs_(2)ZrCl_(6) single crystals to exhibit efficient warm white light emission.This work provides a new perspective for the development and design of stable lead-free perovskites with highly efficient luminescence. | Pengfei Cheng Daoyuan Zheng Lu Feng Yuefeng Liu Junxue Liu Juntao Li Yang Yang Guoxiong Wang Keli Han | 2022 | Journal of Energy Chemistry2022,31,2: | 2 |
| 8 | ESIPT-based AIE luminogens:Design strategies,applications,and mechanisms显示文摘In this review,we present a systematic and comprehensive summary of the recent development and applications of excited-state intramolecular proton transfer-based(ESIPT-based)aggregation-induced emission luminogens(AIEgens),a type of promising materials that inherit the advantages of ESIPT and AIE,such as large Stokes shift,excellent photostability,and low self-quenching.We first summarize the backbones that have been used to construct the ESIPT-based AIEgens and classify the constructed ones based on the relation between ESIPT and AIE unit.According to the sensing mechanisms and design strategies,we have reviewed the applications of ESIPT-based AIEgens in bioimaging,drug delivery systems,organic lightemitting diodes,photo-patterning,liquid crystal,and the detection of metal cations,anions,small molecules,biothiols,biological enzymes,latent fingerprinting,and so on.We have also reviewed the recent advances in the development of new theoretical methods for investigating molecular photochemistry in crystals and their applications in ESIPT-based AIEgens.We discussed the remaining challenges in this field and the issues that need to be addressed.We anticipate that this review can provide a comprehensive picture of the current condition of research in this field,and promote researchers to make more efforts to develop novel ESIPT-based AIEgens with new applications. | Panwang Zhou Keli Han | 2022 | Aggregate2022,3,5: | 2 |

| 10 | Explicit solvent model for spectral shift of acrolein and simulation with molecular dynamics显示文摘By introducing the concept of spring energy of permanent dipole and taking the conforma-tions of solvent molecules into account,the formulas of electrostatic solvation energy in equilibrium and nonequilibrium are derived from the explicit solvent scheme,with the spatial distribution of the discrete permanent charges and induced dipoles of the sol-vent molecules involved. The energy change of sol-ute due to the variation of wave function from the case of vacuum to that in solution is estimated by treating the solvent effect as external field in the it-eration cycles of the self-consistent field. The ex-pression for spectral shift is deduced and applied to the processes of light absorption and emission in solution. According to the new formulations,the av-eraged solvent electrostatic potential/molecular dy-namics program is modified and adopted to investi-gate the equilibrium solvation energy of water mole-cule and spectral shift of acrolein. | ZHU Quan LIU Jifeng FU Kexiang HAN Keli LI Xiangyuan | 2006 | Chinese Science Bulletin2006,51,24: | 1 |
