High-performance ultraviolet detector based on self-assembled 3D/2D perovskite heterostructure.

ABSTRACT: Heterogeneous assembly of metal halide perovskites (MHPs) structures offers convenience for promoting the interfacial properties of perovskite heterojunctions, which have been widely used in the new generation of photoelectric devices. In this study, three-dimensional (3D) CsPbBr₃ quantum dots (CPB QDs) were epitaxially grown on two-dimensional (2D) (BA)₂PbBr₄ nanoplates (BPB NPs) via self-assembly in a toluene mixing solution. The morphological, structural, and optical properties of the synthesized structure reveal that a highly-qualified interface and coherence were formed between the two different perovskites. These heterostructures (HSs) facilitate the separation and transportation of electrons and holes in opposite directions. Based on this prop
