Abstract
Luminescence properties of Eu3+ doped TeO2–PbO–GeO2 glasses containing gold nanoparticles (NPs) were investigated. The emission spectra of the samples exhibited enhancement of Eu3+ luminescence due to the presence of gold NPs. The emission at 614nm, due to the Eu3+ hypersensitive transition 5D0–7F2, is much influenced by the gold NPs and increases by ≈100% for samples heat-treated at 350°C during 41h.
