Germanate-tellurite glasses with a composition of (75-x) TeO₂-xGeO₂–12.5ZnO-12.5BaO, where x = 0, 5, 10, and 20 mol%, were synthesized. A traditional melt-quenching-annealing process was used to fabricate these glasses, at 1000 °C for melting and 300 °C for five hours for annealing. X-ray diffraction was used to investigate the structural features of each sample between 10 °C and 80 °C to prove the amorphous nature of these glasses. Moreover, Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) was employed to explore the functional groups of Te, Ge, and other elements. To study the transparency, cut-off wavelength, and other optical properties of the glasses, such as indirect, direct, and Urbach energy band gaps, optical absorption was measured in the range of 200–800 nm. Additionally, the radiation shielding properties for the germanium based-tellurite glasses were calculated using Monte Carlo N particle transport code (MCNP-5). The simulated results were compared with XCOM software and the results between the two methods closely agreed. The maximum mass attenuation coefficient varied between 47.305 and 50.620 cm2.g ^− 1 for TG1 and TG4 glasses respectively at 0.015 MeV. The effective atomic number (Z_eff) for the prepared germanium based-tellurite glasses was evaluated and the results revealed that the maximum Z_eff values were found at 0.04 MeV, varying between 48.24 and 49.98 for TG4 and TG1.

组成为（75-x）TeO ₂ -xGeO ₂ –12.5ZnO-12.5BaO的锗酸盐-碲酸盐玻璃，其中x 合成＝ 0、5、10和20mol％。使用传统的熔体淬火退火工艺来制造这些玻璃，在1000°C熔化，在300°C退火5小时。X射线衍射用于研究10°C至80°C之间每个样品的结构特征，以证明这些玻璃的非晶性。此外，衰减全反射傅立叶变换红外（ATR-FTIR）用于研究Te，Ge和其他元素的官能团。为了研究玻璃的透明性，截止波长和其他光学特性，例如间接，直接和Urbach能带隙，在200-800 nm范围内测量了光吸收。另外，使用蒙特卡罗N粒子传输代码（MCNP-5）计算锗基碲酸盐玻璃的辐射屏蔽性能。仿真结果与XCOM软件进行了比较，两种方法之间的结果非常吻合。最大质量衰减系数在47.305和50.620 cm2之间变化。克 ^{-  1}为TG1和TG4分别眼镜在0.015兆电子伏。对制备的锗基碲酸盐玻璃的有效原子序数（Z _eff）进行了评估，结果表明，最大的Z _eff值为0.04 MeV，TG4和TG1在48.24至49.98之间变化。
