摘要

Single materials generating high-efficiency white light emission are of particular interest for lighting.Recently,metal halide perovskite is emerging as a promising candidate for white light emission materials.However,lead halide perovskites showing broad spectrum light emission generally present low luminescence quantum yield and the emission spectrum deviates from the standard white light color coordinate.On the other hand,the mechanism for the formation of self-trapped exciton (STE) giving rise to broad emission is not clarified [1].
