Abstract

The influence of erbium (Er3+) ion concentration on the infrared emission at 1.5 μm in TeO2-WO3 and TeO 2-CdO-WO3 glasses was studied. The samples were prepared by conventional melt quenching method. The optical properties were studied by measuring the absorption and luminescence spectra at room temperature. The Judd-Ofelt parameters (Ωt), transition probabilities, branching ratios of various transitions and their radiative lifetimes were calculated from the optical absorption spectra. Absorption and emission cross-section spectra and the Stark Levels splitting for the 4I13/2 to 4I15/2 transition of Er3+ centered at 1.5 μm were determined.
