Paper Abstract

In this paper antimony-germanate oxide glasses doped with Er3+ and co-doped with Er3+/Ag ions were synthesized and measured in terms of absorbance and near-infrared emission parameters. Series of glasses with different molar concentration of erbium oxide led to the optimal rare earth ion content equal to 0.8 mol% Er2O3. The effect of the incorporation silver ions to the glass matrix on the absorption spectrum in the UV range (Ag: S0 → S1, 350 nm) was confirmed formation of silver ions as a nanoparticles or nanoclusters. In samples co-doped with Er3+/Ag ions decrease of near-infrared luminescence intensity has been observed indicating predominant energy transfer from erbium to silver ions (Er3+ → Ag).
