CsPbBr_1.5I_1.5 quantum dots (QDs) glasses are synthesized by traditional melting and thermal treated method, CsPbBr_1.5I_1.5 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, Eu³⁺ ions is chosen to introduce into CsPbBr_1.5I_1.5 QDs, the quantum yield is enhanced to 64.7%. After a sequence of testing operations, we find that 6.5%CsPbBr_1.5I_1.5:0.28%Eu³⁺ QDs glasses is a strong competitor among red fluorescence solid materials.

Eu3 +掺杂的CsPbBr1.5I1.5量子点玻璃：红色荧光固体材料中的强大竞争者

CsPbBr _1.5 I _1.5量子点（QDs）玻璃是通过传统的熔化和热处理方法合成的，CsPbBr _1.5 I _1.5 QDs玻璃由于其中等的发射波长和良好的不透明性，在温暖的WLED应用中显示出作为红色荧光成分的巨大潜力。然而，量子点玻璃的量子产率仍然较低，因此，选择Eu ³⁺离子引入CsPbBr _1.5 I _1.5量子点中，量子产率提高到64.7％。经过一系列测试操作，我们发现6.5％CsPbBr _1.5 I _1.5：0.28％Eu ³⁺ QDs眼镜是红色荧光固体材料中的强大竞争者。
