Resumen

We report a systematic study of the localized surface plasmon resonance effects on the photoluminescence of Er3 +-doped tellurite glasses containing Silver or Gold nanoparticles. The Silver and Gold nanoparticles are obtained by means of reduction of Ag ions (Ag+ → Ag0) or Au ions (Au3 + → Au0) during the melting process followed by the formation of nanoparticles by heat treatment of the glasses. Absorption and photoluminescence spectra reveal particular features of the interaction between the metallic nanoparticles and Er3 + ions. The photoluminescence enhancement observed is due to dipole coupling of Silver nanoparticles with the 4I13/24I 15/2 Er3 + transition and Gold nanoparticles with the 2H11/24I13/2 (805 nm) and 4S3/24I13/2 (840 nm) Er 3 + transitions. Such process is achieved via an efficient coupling yielding an energy transfer from the nanoparticles to the Er3 + ions, which is confirmed from the theoretical spectra calculated through the decay rate.
