Photoluminescent Properties of Phosphor Based on Perovskite CsPbBr(3) Nanocrystals Combined with Violet Leds

The characteristics of an LED lighting system consisting of a commercial violet LED and a green phosphor based on CsPbBr(3) nanocrystals are studied in the context of development of LED illumination sources with antibacterial effects but without harmful effects on human health. The internal efficien...

description The characteristics of an LED lighting system consisting of a commercial violet LED and a green phosphor based on CsPbBr(3) nanocrystals are studied in the context of development of LED illumination sources with antibacterial effects but without harmful effects on human health. The internal efficiency of the nanocrystalline phosphor in a silicone compound was found to exceed 40%, dropping noticeably because of heating for an electric current of ~0.1 A (phosphor excitation intensity ~0.1 W/mm(2)). This undesirable feature can be diminished by using a remote phosphor design for the illuminators and by using chemical techniques to improve the thermal stability of the nanocrystals
