摘要	Yb3+/Ho3+ codoped and Yb3+/Er3+/Ho3+ tridoped TeO2–BaF2–LaF3–La2O3 (TBLL) fluorotellurite glasses with low OH− absorption (0.026 cm-1), high glass transition temperature (434 °C) and low phonon energy (784 cm-1) were prepared. Their mid-infrared fluorescence properties and related energy transfer (ET) mechanism were studied under 980 nm excitation. A strong emission at 2.85 μm was realized in Yb3+/Ho3+ codoped tellurite glass, which was attributed to the high-efficiency ET from Yb3+ ions to Ho3+, and the ET efficiency was 91.1%. Further introduction of Er3+ ions induced stronger 2.85 μm emission, and the ET efficiency was improved to 96.2%, ascribed to the establishment of more ET channels and Er3+ ions playing the role of ET bridge between Yb3+ and Ho3+ ions. These results indicate that the Yb3+/Er3+/Ho3+ tridoped tellurite glass could be a hopeful gain medium material for the ∼3 μm fiber laser. © 2021
