Resumen

We show the annealing effect on silver and Erbium- doped tellurite glasses in the formation of nanoparticles (NPs) of silver, produced by the reduction of silver (Ag⁺→Ag⁰), aiming to an fluorescence enhancement. The absorption spectra show typical Localized Surface Plasmon Resonance (LSPR) band of Ag⁰ NP in addition to the distinctive absorption peaks of Er³⁺ ions. Both observations demonstrate that the photoluminescence enhancement is due to the coupling of dipoles formed by NPs with the Er³⁺ ⁴I_13/2→⁴I ^15/2 transition. This plasmon energy transfer to the Er³⁺ ions was observed in the fluorescence spectrum with a blue-shift of the peaks.
