Unfolding the role of local cation heterogeneities on the phase segregation a...

Mixed-halide perovskites suffer from light-induced segregation, forming halide-rich domains with different bandgaps. Local techniques show local heterogeneities in the...混合卤化物钙钛矿（mixed-halide perovskites）易出现光诱导分相现象，进而形成带隙（bandgaps）各不相同的富卤域。局域表征技术可揭示其内部存在的局域异质性……
