主 题：Metal halide perovskite Self assembly Nanostructures Surface ligand|Solvent effects
摘 要：The self-assembled metal halide perovskite(MHP)nanocrystal superlattices have attracted many researchers due to their exceptional optical and electrical *** bottom-up self-assembly can be facile to generate ideal and periodic *** superlattices’stability can be improved and the photoluminescence lifetime can be extended by an order of ***,due to lack of a comprehensive and systematic understanding of the internal interactions on self-assembled processes now,superlattices cannot be obtained controllably and play full use of their ***,gaining a deep insight of interaction forces about self-assemblies is the premise of designing and controlling the degree of self-assembly so as to prepare ideal *** this review,the definitions and functions of driving forces including van der Waals forces,electrostatic interactions and hydrogen bonds are ***,we aim to explore the dominant factors affecting the driving forces,which can make a difference in the process of MHP *** on current researches,we emphasize on three aspects−the core of nanocrystals,surface ligands and solvents−to clarify their critical roles in controlling the driving ***,the outlooks and perspectives of how to facilitate the MHP self-assembly and their application on blue light emitting diodes are discussed.
