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