摘　　要：有机无机杂化钙钛矿(Organic-inorganic hybrid perovskites,OIHP)由于易受电子辐射损伤,在利用电镜对其进行材料学研究分析时具有一定的局限性。在利用透射电镜对其分析时建议使用高加速电压,但在利用扫描电镜分析时有建议用高加速电压,也有建议用低加速电压,观点不一。本研究以有机无机杂化钙钛矿MAPbBr3为代表样品,对OIHP利用扫描电镜成像条件进了探讨。Due to electron radiation damage,there are some limitations in the research and analysis of organic-inorganic hybrid perovskites(OIHP)by electron microscope.It is suggested to use high accelerating voltage when analyzing OIHP by TEM.However,there are different views on whether to use high accelerating voltage or low accelerating voltage when analyzing OIPH by SEM.Taking MAPbBr3as a representative sample,the imaging conditions of OIPH using SEM were discussed in this paper.
