| Abstract |
| Er3+ doped boro-tellurite glasses with the chemical composition (40–x)B2O3+30TeO2+10Na2O+10ZnO+
5Li2O+5CaO+xEr2O3 (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 (P), branching
ratios (R) and radiative lifetime (cal) were calculated for the 4I13/2 4I15/2 transition and the results were presented.
