Glasses doped with CsPbBr3 quantum dots (QDs) were prepared by a conventional melt-quenching process followed by heat treatment, which exhibit good thermal stabilities and optical properties. A narrow visible photoluminescence (PL) emission (508–528 nm) band with a shift in luminescence peak position and a significant change in emission intensity was observed, depending on the B2O3 concentration. Transmission electron microscopy (TEM) showed changes in the size and number of QDs with change in glass composition. The PL decay time was about 0.92–1.58 us, and it showed an increasing trend with increasing size of the QDs. With decreasing concentration of B2O3, the network structure of the glass exhibit a high aggregated state, thus providing sufficient growth space to the QDs. The luminescence of the QDs glass was found to be controlled by changing glass topology. The tunable narrow band emission of CsPbBr3 QDs doped glass may have potential applications in new generation of display materials.
