摘要：
Er3+ doped boro-tellurite glasses with the chemical composition (40-x) B2O3+ 30TeO(2)+ 10Na(2)O+ 10ZnO+ 5Li(2)O+ 5CaO+ xEr(2)O(3) (where x = 0.01, 0.1, 1, 2 and 3 wt%) were prepared by conventional melt quenching technique. The spectroscopic analyses were made through absorption and luminescence measurements. From the absorption spectra, bonding parameters, oscillator strengths and Judd-Ofelt (JO) parameters were calculated. Through the luminescence spectra the various lasing parameters such as stimulated emission cross-section (sigma(P)), branching ratios (beta(E)(R)) and radiative lifetime (tau(cal)) were calculated for the I-4(13/2) -> I-4(15/2) transition and the results were presented.
