Abstract

Ag nanoparticles (NPs) and ${\mathrm{CsPbBr}}_3$ perovskite quantum dots (QDs) are precipitated in a borosilicate glass by the conventional melt-quenching method, which has outstanding stability benefited from the amorphous oxide matrix. X-ray diffraction, X-ray photoelectron spectroscopy, and transmission electronic microscopy results show that part of ${\mathrm{Ag}}^{+}$ ions replace ${\mathrm{Pb}}^{2+}$ ions in the ${\mathrm{CsPbBr}}_3$ QDs, and the other ${\mathrm{Ag}}^{+}$ ions convert into Ag NPs. The presence of these Ag-species results in enhanced photoluminescence total intensity by 5 times for the ${\mathrm{CsPbBr}}_3$ QD-doped glasses, explained by the accelerated growth of QDs and the Ag NPs-induced plasmonic near-field effect.
