Abstract

In this talk, I will present our recent efforts on the development of new materials and processing approaches to achieve efficient and stable perovskite light emitting diodes (LEDs) with tunable colors. First, surface passivation of metal halide perovskite nanocrystals will be discussed, which could not only reduce surface defects, but also protect the surface from the penetration of degradation agents (e.g. moisture). Second, a novel approach to achieve efficient blue emissions from hollow perovskite nanocrystals via quantum size effects will be introduced. Lastly, processing engineering to prepare metal halide perovskite thin films with desired morphological and electronic properties for LEDs will be discussed.
