The influence of erbium (Er3+) ion concentration on the infrared emission at 1 5 mu m in TeO2-WO3 and TeO2-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 (Omega(t)) 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 I-4(13/2) to I-4(15/2) transition of Er3+ centered at 1 5 mu m were determined (C) 2010 Elsevier BV All rights reserved
