摘要
介绍了二维钙钛矿的结构以及其对应的独特光激子性质。介绍了光谱中声子的特性,分析了强的电声相互作用可能是以n=3为主的混合二维钙钛矿适合作为光电材料的物理原因。最后,根据前文介绍探讨了需要进一步厘清的问题,以期为优化二维钙钛矿光电材料和器件提供思路。
The structure of two-dimensional perovskites and their corresponding unique exciton properties were introduced,especially the characteristics of phonon in the spectrum. It was analyzed that the strong electron-phonon interaction may be the physical reason why n=3-based mixed two-dimensional perovskites were suitable for photoelectric materials. Finally,the further problems were clarified in order to provide ideas for the optimization of two-dimensional perovskite optoelectronic materials and devices.
