The lead halide-based perovskites,for instance,CH_3NH_3PbX_3 and CsPbX_3(X = Cl,Br,I),have received a lot of attention.Compared with bulk materials,low-dimensional perovskites have demonstrated a range of unique optical,electrical and mechanical properties,which enable wide applications in solar cells,lasers and other optoelectronic devices.In this paper,we provide a summary of the research progress of the low-dimensional perovskites in recent years,from synthesis methods,basic properties to their optoelectronic applications.
