研究了Ho3+/Yb3+掺杂的氟锗酸盐玻璃在980 nm激光二极管抽运下的中红外2.0 μm、2.85 μm和可见上转换发光特性以及两种稀土离子之间的能量转移机理。在氟锗酸盐玻璃中掺杂1%（物质的量分数） Ho2O3和9%Yb2O3的样品中，获得了增强的中红外2.0 μm和2.85 μm发光。测得Ho3+的2.0 μm荧光寿命为6.19 ms，理论计算得到Ho3+在2023 nm处最大发射截面面积为6.6×10-21 cm2。研究结果表明，Ho3+/Yb3+掺杂的氟锗酸盐玻璃是一种合适的中红外2.0 μm和2.85 μm 激光材料。

Emission properties of mid-infrared at 2.0 μm and 2.85 μm, and visible up-conversion as well as energy transfer mechanism between two rare earth ions, Ho3+ and Yb3+, are studied in Ho3+/Yb3+ co-doped fluorogermanate glasses pumped by a 980 nm laser diode. Enhanced mid-infrared 2.0 μm and 2.85 μm emission is obtained in fluorogermanate glass samples which is co-doped with 1% Ho2O3 and 9% Yb2O3(mole fractions). The measured decay lifetime of Ho3+ is 6.19 ms, and the theoretically calculated maximum emission cross section at 2023 nm is about 6.6×10-21 cm2. The results indicate that Ho3+/Yb3+ co-doped fluorogermanate glasses are suitable for mid-infrared 2.0 μm and 2.85 μm emission.
