摘要：
Glasses of the system 75TeO2–20ZnO–5La2O3–0.8Tm2O3–xYb2O3 were prepared by high temperature melt cooling method. Results of differential scanning calorimetry indicate that, all glass samples have excellent thermal stability. Judd–Ofelt strength parameters, spontaneous emission probabilities, fluorescence branching rations, fluorescence radiative lifetime of Tm3+ ions in tellurite glass were calculated. The impact of Yb3+ concentration on the fluorescence properties of Tm3+ ions in the S band under the pumping wavelength of 465 nm was investigated in a suggestion that, 3H4 radiative lifetimes will be prolonged and the performance of optical amplifier gain of Tm3+ in tellurite glass co-doped with 0.5 mol % Yb3+ ions will be improved.
