•A kind of new fluoroaluminate–tellurite glass is prepared.•The thermal ability of fluoroaluminate is improved a lot by adding TeO2.•The structure of fluoroaluminate–tellurite is investigated.•The change of near-infrared luminescence properties caused by TeO2 has been investigated.•The new fluoroaluminate–tellurite glass has good spectroscopic properties, bandwidth characteristics and gain performances.
In this work, the thermal and spectroscopic properties of Er3+-doped oxyfluorite glass based on AMCSBYT (AlF3–MgF2–CaF2–SrF2–BaF2–YF3–TeO2) system for different TeO2 concentrations from 6 to 21 mol% is reported. After adding a suitable content of TeO2, the thermal ability of glass improves significantly whose ΔT and S can reach to 118 °C and 4.47, respectively. The stimulated emission cross-section reaches to 7.80 × 10−21 cm2 and the fluorescence lifetime is 12.18 ms. At the same time, the bandwidth characteristics reach to 46.41 × 10−21 cm2 nm and the gain performance is 63.73 × 10−21 cm2 ms. These results show that the optical performances of this oxyfluorite glass are very well. Hence, AMCSBYT glass with superior performances might be a useful material for applications in optical amplifier around 1.53 μm.
