摘要: Abstract The influence of erbium (Er 3+ ) ion concentration on the infrared emission at 1.5 μm in TeO 2 –WO 3 and –CdO–WO glasses was studied. samples were prepared by conventional melt quenching method. optical properties studied measuring absorption luminescence spectra room temperature. Judd–Ofelt parameters (Ω t ), transition probabilities, branching ratios various transitions their radiative lifetimes calculated from spectra. Absorption cross-section Stark Levels splitting for 4 I 13/2 to 15/2 Er centered determined.
