Abstract

Organometal halide perovskites, as promising semiconductor materials for achieving future low-cost optoelectronic devices, suffer from inherent instability and undergo extremely fast degradation under exposure to moisture, UV light, or high temperature. Herein, we present a facile and low cost approach for the preparation of perovskite-based composite films via blending CH3NH3PbBr3 nanocrystals (MAPbBr3 NCs) with two kinds of commercially available silicone resins. The highest photoluminescence quantum yield of the prepared composite films is up to 62%. The composite films of MAPbBr3 NCs with phenyl methyl silicon resin (PMSR) show unprecedented stability against water, heat and UV exposure. Their applications as paints or as phosphors for the fabrication of green and white light LEDs are demonstrated.
