摘　　要：Low-dimensional hybrid lead-halide perovskites with broadband white-light emission upon near-UV excitation have attracted immense scientific interest due to their potential application for the next generation of solid-state lighting as well as scintillators for radiation detection.Recently,broadband emission material is mostly reported in structural distorted perovskites.However,it is still unclear how to generate structural distortion in low-dimensional perovskites.
