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