摘要

Phosphate glasses with a high concentration of Nd3+ ions are key components for the development of efficient near-infrared (NIR) laser systems. The sensitization of Nd3+ ion luminescence in BaO–P2O5 glass using Ag nanoaggregates is investigated in this study. The results show that the thermally stimulated formation of \({\text{Ag}}_{m}^{n+}\) Ag m n + molecular clusters allow a 15-fold enhancement of the photoluminescence intensity of Nd3+ ions, whereas the formation of plasmonic nanoparticles (NPs) did not achieve such an enhancement. These results open new perspectives for controlling the properties of phosphate glasses and improving the efficiency of laser systems.
