Broadband white-light emission was realized in a polar two-dimensional hybrid perovskite, (2meptH2)PbBr4 (2mept = 2-methyl-1,5-diaminopentane). The white-light emission originates from self-trapped excitons owing to the distortion-induced polar structure. Notably, it exhibits a high photoluminescence quantum efficiency of 3.37% and an ultrahigh colour rendering index of 91.
在极性二维杂化钙钛矿(2meptH2)PbBr4（2mept = 2-甲基-1,5-二氨基戊烷）中实现了宽带白光发射。由于畸变诱导的极性结构，白光发射源自自陷激子。值得注意的是，它表现出3.37%的高光致发光量子效率和91的超高显色指数。
