Nonlinear Absorption and Low-threshold Two-photon Pumped Amplified Stimulated Emission from FAPbBr3 Nanocrystals
甲脒铅溴(FAPbBr3)钙钛矿纳米晶因其更标准的绿光发射、优异的稳定性和载流子传输特性而被认为是一种良好的光电材料.然而,FAPbBr3纳米晶体的双光子泵浦放大自发辐射(ASE)和相应的非线性光学特性却很少被报道.本文在室温下通过改变前驱体溶液中FABr/PbBr2的摩尔配比,利用配体辅助沉淀(LARP)技术合成了不同尺寸的胶体FAPbBr3纳米晶体.测量了光致发光(PL)和时间分辨光致发光光谱(TRPL),以表征其ASE特性.并利用Z扫…查看全部>>
Formamidinium lead bromide (FAPbBr3) nanocrystals (NCs) have been considered to be a good opto-electronic material due to their pure green emission,excellent stability and superior carrier transport characteristics.However,two-photon pumped amplified spontaneous emission (ASE) and the corresponding nonlinear optical prop-erties of FAPbBr3 NCs are scarcely revealed.Herein,we synthesized colloidal FAPbBr3 NCs with different sizes by changing the molar ratio of…查看全部>>
