Abstract

Abstract : CsPbBr3 QD glasses heat-treated at different temperatures have different sizes of QDs and lasing properties. Abstract : By increasing the heat treatment temperature, the average size of CsPbBr3 quantum dots (QDs) in the glass matrix was increased, which contributed to a 5.5 fold increase of the optical gain coefficients. And the corresponding lasing threshold decreased from 0.752 mJ cm −2 to 0.138 mJ cm −2 .
