Long-term stable stacked CsPbBr3 quantum dot films for highly efficient white light generation in LEDs

Author affiliations

Abstract

We report highly efficient ethyl cellulose with CsPbBr3 perovskite QD films for white light generation in LED application. Ethyl cellulose with CsPbBr3 quantum dots is applied with Sr2Si5N8 : Eu2+ red phosphor on an InGaN blue chip, achieving a highly efficient luminous efficacy of 67.93 lm W−1 under 20 mA current.
