摘要：

Pr3+ ion doped TeO2 glasses were synthesized by standard melt quenching method. Optical absorption, photoluminescence and decay profiles were recorded to assess the luminescence efficiency of Pr3+ ions in Sb2O3-WO3 mixed tellurite glasses. Judd-Ofelt theory was applied to evaluate radiative properties and also the varying environment of the rare earth ion with varying concentration of Pr3+ ions in the glass matrix. Luminescence spectra recorded in the visible region exhibited several emission transitions and among them the red luminescence transition P-3(0) -> F-3(2) is found to be more intense. Variations of luminescence intensity and life times of excited state energy levels with the concentrations of Pr3+ ions are discussed in the light of variation in the environment of Pr3+ ions in the glass network.
