制备了新的Er3+/Yb3+共掺氟氧硅酸盐微晶玻璃,测试了荧光光谱、吸收光谱。研究了氟氧化物微晶玻璃中Er3+离子的上转换发光特性，采用Judd-Ofelt理论对样品光谱进行了分析，拟合得到了强度参数，Ω2=4.4756，Ω4=1.0059，Ω6=1.2098。计算了样品的辐射寿命、跃迁几率、荧光分支比等光谱参数。结果表明，样品通过热处理形成了氟化物微晶，降低了声子能量，提高了上转换效率。绿光、红光上转换荧光强度比玻璃样品增强约2到3倍。Judd-Ofelt理论分析表明Er3+/Yb3+共掺氟氧微晶玻璃具有较高的上转换效率，是制作微型激光器和三维立体显示的优良材料之一。

Using the oxyfluoride silicate glass ceramics co-doped Er3+/Yb3+ ions, this paper tested fluorescence spectroscopy, absorption spectroscopy. The up-conversion luminescence properties of the Er3+ ion in the oxyfluoride glass-ceramics were studied, with analysis on the spectra of samples with Judd-Ofelt theory, and the intensity parameters are obtained, Ω2=4.4756, Ω4=1.0059, Ω6=1.2098. Radiative lifetimes of samples, transition probabilities, and fluorescence branching ratio spectral parameters are concluded. The results show that the samples formed fluoride microcrystal by heat treatment, which lower phonon energy and greatly improve the up-conversion efficiency. The infrared to green or to red up conversion luminescence intensities for the glass-ceramics are evaluated to be nearly 2 to 3 times as high as that of aluminosilicate glasses. Judd-Ofelt theory show that theoxyfluoride glass-ceramics co-doped Er3+/Yb3+ ions have high up-conversion efficiency, and it is one of fine materials for the production of micro-laser and three-dimensional display.
