摘要：

Ag nanoparticles (NPs) and CsPbBr3 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 Ag+ ions replace Pb2+ ions in the CsPbBr3 QDs, and the other Ag+ ions convert into Ag NPs. The presence of these Ag-species results in enhanced photoluminescence total intensity by 5 times for the CsPbBr3 QD-doped glasses, explained by the accelerated growth of QDs and the Ag NPs-induced plasmonic near-field effect.
