Abstract

Abstract: CsPbBr1.5 I1.5 quantum dots (QDs) glasses are synthesized by traditional melting and thermal treated method, CsPbBr1.5 I1.5 QDs glasses show vast potential as red fluorescence component in warm WLED applications due to their moderate emission wavelength as well as good opacity property. However, the quantum yield of QDs glasses is still low, therefore, Eu 3+ ions is chosen to introduce into CsPbBr1.5 I1.5 QDs, the quantum yield is enhanced to 64.7%. After a sequence of testing operations, we find that 6.5%CsPbBr1.5 I1.5 :0.28%Eu 3+ QDs glasses is a strong competitor among red fluorescence solid materials.
