Abstract
In recent years, inorganic perovskite quantum dots (PQDs) have garnered significant attention, but the photoluminescence (PL) properties and stability of red-emitting PQDs need to be further enhanced. In this work, the precipitation of CsPb(Br/I)3 quantum dots into borosilicate glass was effectively enabled by the high-temperature melt-quenching method. With the B2O3/SiO2 ratio increased, the glass network structure gradually loosened, which enhanced the precipitation of PQDs. Simultaneously, the PL intensity of CsPb(Br/I)3 PQDs glass increased, with a near twentyfold rise in the photoluminescence quantum yield (PLQY). The variable temperature test of PQDs glass shows that PQDs glass has good thermal stability. Finally, a red-emitting LED and a WLED were prepared by using the prepared red-emitting CsPb(Br/I)3 PQDs glass. This paper serves as a reference for incorporating red-emitting CsPb(Br/I)3 PQDs glass into WLED development.
期刊介绍：
The Journal of Alloys and Compounds is intended to serve as an international medium for the publication of work on solid materials comprising compounds as well as alloys. Its great strength lies in the diversity of discipline which it encompasses, drawing together results from materials science, solid-state chemistry and physics.
