The influence of erbium (Er 3+ ) ion concentration on the infrared emission at 1.5 μm in TeO 2 -WO 3 and TeO 2 -CdO-WO 3 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 r
