Review summarizes recent advancements in metal halide perovskites' structural and optoelectronic properties, highlighting practical applications.
Metal halide perovskites (MHPs), in the form of nanocrystals (NCs) and their superlattices (SLs), have attracted substantial attention owing to their outstanding optoelectronic properties, solution processability, and emergent collective phenomena. In particular, MHP NCs, characterized by bright triplet excitons, slow exciton dephasing, and minimal spectral inhomogeneity, constitute an ideal platform for investigating collective coupling. This review provides a concise overview of MHP NCs and SLs, ranging from assembly-unit design to functional supermaterials. Starting from individual MHP NCs, this review summarizes recent advances in SL formation and structural diversity, highlights key collective optoelectronic phenomena, and discusses representative device applications.
