Abstract
AbstractCsPbI3 perovskite quantum dots (QDs) doped borosilicate glass was prepared by the process of melt‐quenching and subsequent annealing. With the introduction of ZnO to the parent glass as the glass network intermediate, the optical properties of the resultant samples are dramatically enhanced. Both the photoluminescence (PL) intensity and photoluminescence quantum yield (PLQY) shows a strong dependence on ZnO concentration as ZnO is found to facilitate the precipitated of the QDs by reducing the connectivity of three‐dimensional glass network built from SiO4 tetrahedrons. The tunable visible‐band PL emission of the CsPbI3 QD‐doped glass could find potential applications in white LEDs and lasers.
