| Resumo |
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 614 nm. due to the Eu3+ hypersensitive transition D-5(0)-F-7(2), is much influenced by the gold NPs and increases by approximate to 100%. for samples heat-treated at 350 degrees C during 41 h.
