- Abstract
- Inorganic halide perovskite (CsPbX3, X = Cl, Br, and I) nanocrystals (PNCs) have been highly sought-after materials in recent years owing to their numerous applications in optoelectronic devices. One such application is white light generation for displays and low-cost light sources. Nevertheless, the poor structural and chemical stabilities of these NCs under environmental factors, such as moisture and oxygen, hinder the fabrication of white light-emitting devices. The improved stability of halide PNCs has been mainly achieved by encapsulating them in robust matrices such as oxide materials, inorganic glass, and metal-organic frameworks. This review summarizes how various encapsulating strategies improve the structural stability of halide PNCs and preserve their bright luminescence characteristics, which aids in the fabrication of high-power white light-emitting diodes. Considering that the NCs are characterized by an inorganic perovskite core and an organic surface layer, we discuss their various structural and surface aspects in this review.
