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 eff ects but without harmful eff ects on human health. The internal effi ciency 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

In the context of development of LED luminaries with antibacterial effect but without harmful effects on human health, the characteristics of an LED lighting system consisting of a commercial violet LED and a green phosphor based on CsPbBr3 nanocrystals are studied. Internal efficiency of the nanocrystalline phosphor in a silicone compound was found to exceed 40% falling down noticeably because of heating for electric current of the order of 0.1 A (excitation intensity of the order of 0.1 W/mm2). This nondesirable feature can be diminished using remote phosphor design of luminaries as well as by rising thermal stability of nanocrystals with chemical techniques.
