Two series of borogermanate-tellurite glasses with compositions of (100-x)[35B₂O₃-10GeO₂-55TeO₂]-xGd₂O₃ and 28.875B₂O₃-8.25GeO₂-45.375TeO₂-(17.5-y)Gd₂O₃-yTb₂O₃ were prepared by melt-quenching method, respectively. The structural and optical properties of those glasses were studied by differential thermal analysis (DTA), Raman, Fourier transform infrared (FTIR), transmittance, photoluminescence, and X-ray excited luminescence spectra together with fluorescence decay curves in details. The DTA results show that Gd₂O₃-enriched borogermanate glass has better structural stability. With the elevated Gd₂O₃ content in borogermanate-tellurite glass, the depolymerization of 6- or 4-membered Ge^[IV] ring into 3-membered one is progressively accelerated, together with an increasing number of isolated groups with short Te–O bonds judging from both the FTIR and Raman spectra. The optical performance of the borogermanate-tellurite glass reaches the best when the Tb₂O₃ content is 7.5 mol% based on both 378 nm ultraviolet light and X-rays excitation. Meanwhile, the scintillation efficiency of the optimized glass, with density of 5.05 g/cm³ and lifetime of 1.328 ms, is about 9.10% of the standard bismuth germinate (BGO) scintillator.

两个系列的硼锗酸盐-碲酸盐玻璃，其成分为 (100- x )[35B ₂ O ₃ -10GeO ₂ -55TeO ₂ ]- x Gd ₂ O ₃和 28.875B ₂ O ₃ -8.25GeO ₂ -45.375TeO ₂ -(17. - y )Gd ₂ O ₃ -yTb ₂ O ₃分别采用熔融淬火法制备。通过差热分析(DTA)、拉曼、傅里叶变换红外(FTIR)、透射率、光致发光和X射线激发发光光谱以及荧光衰减曲线详细研究了这些玻璃的结构和光学性质。DTA结果表明，富含Gd ₂ O _{3 的}硼锗酸盐玻璃具有更好的结构稳定性。随着硼锗酸盐-碲酸盐玻璃中Gd ₂ O ₃含量的增加，6 或 4 元 Ge 的解聚^[IV]从 FTIR 和拉曼光谱判断，环成 3 元的环逐渐加速，同时越来越多的具有短 Te-O 键的孤立基团。基于378 nm紫外光和X射线激发，当Tb ₂ O ₃含量为7.5 mol%时，硼锗酸盐-碲酸盐玻璃的光学性能达到最佳。同时，密度为5.05 g/cm ³、寿命为1.328 ms的优化玻璃的闪烁效率约为标准铋萌发（BGO）闪烁体的9.10%。
