二维钙钛矿结构调控及光物理性能研究进展
|
摘要
传统的三维(3D)有机-无机卤化物钙钛矿经历了前所未有的快速发展。然而,它们对水分、光和热的固有不稳定性仍然是限制其商业化发展的关键问题。相比之下,新出现的二维(2D)钙钛矿因其巨大的环境优势而受到越来越多的关注。然而,对二维钙钛矿的研究还处于起步阶段,其结构和光物理特性仍有待深入探索。首先,介绍了二维杂化钙钛矿的结构;然后,对该结构中有机胺以及无机元素的选择进行比较讨论,并对二维杂化钙钛矿中独特的激子性质、电声耦合以及自旋轨道耦合(SOC)效应等方面的研究进行了总结;最后,根据前文论述指出下一步研究需要解决的问题,以期为将来开发和制备性能更优异的二维钙钛矿光电器件提供参考。
Traditional three-dimensional(3D)organic-inorganic halide perovskites experience unprecedented rapid development.However,the inherent instability of the traditional three-dimensional organic-inorganic halide perovskites to moisture,light and heat remains a key issue limiting their commercial development.In contrast,the emerging two-dimensional(2D)perovskite draws more and more attentions due to its huge environmental advantages.While,the research on the two-dimensional perovskite is still in its infancy,and its structural and photophysical properties remain to be further explored.The structure of the two-dimensional hybrid perovskite is introduced firstly.Then,the selection of organic ammonia and inorganic elements in the two-dimensional hybrid perovskite is compared and discussed.Besides,the researches on the unique properties of the exciton,electron-phonon coupling and spin-orbit coupling(SOC)effect in the two-dimensional hybrid perovskite are summarized.Finally,according to the previous discussion,the problems to be solved in the next step are pointed out,so as to provide a reference for the development and preparation of two-dimensional perovskite optoelectronic devices with better performances in the future.
