In this study, we examined the effectiveness of europium-doped calcium gadolinium silicoborate glasses for determining their physical, mechanical, acoustic and radiation shielding properties with compositions of 25GdO–10CaO–10SiO-xEuO -(55-x) BO (where, x is 0.1, 0.2, 0.3, and 0.4 mol%). These glasses were theoretically analyzed using the Geant4 toolkit and Phy-X PSD software to calculate their performance for x-ray energies ranging from 0.2 to 1.2 MeV. The physical, acoustic and mechanical properties were determined using the Makishima-Mackenzie (MM) model. As the content of EuO increases, the density of the glasses also increases. As the amount of EuO increases, the mechanical properties decrease. This means that certain mechanical properties of the material may be negatively affected, resulting in a decreased ability to maintain structural integrity and resist deformation when exposed to radiation. The elastic modulus reflects the material's stiffness or rigidity, and a lower value indicates that the material is more prone to deformation when subjected to mechanical stress. Bulk and Young's moduli show a decreasing trend from 255.49 to 253.10 GPa and 368.20 to 366.50 GPa with increasing Eu concentration in the glass samples. The LAC values of EuGd4 glass is much smaller when compared to the other glasses. The presence of gadolinium and europium compounds in the glass increases its ability to absorb radiation due to the elements of high atomic numbers. This is because the higher effective atomic number (Z) of these compounds enhances the glass of shielding capabilities against neutron and gamma rays, resulting in improved radiation protection.

稀土氧化物（Eu2O3）对CaO-Gd2O3-SiO2-B2O3玻璃物理、机械、声学和辐射屏蔽性能的影响

在这项研究中，我们研究了掺铕硅硼酸钙钆玻璃的有效性，以确定其物理、机械、声学和辐射屏蔽性能，其成分为 25GdO–10CaO–10SiO-xEuO -(55-x) BO（其中，x 是0.1、0.2、0.3 和 0.4 摩尔%）。使用 Geant4 工具包和 Phy-X PSD 软件对这些玻璃进行了理论上分析，以计算其在 0.2 至 1.2 MeV 范围内的 X 射线能量下的性能。使用 Makishima-Mackenzie (MM) 模型确定物理、声学和机械特性。随着EuO含量的增加，玻璃的密度也增加。随着EuO含量的增加，机械性能下降。这意味着材料的某些机械性能可能会受到负面影响，导致暴露在辐射下时保持结构完整性和抵抗变形的能力下降。弹性模量反映了材料的刚度或刚度，较低的值表明材料在受到机械应力时更容易变形。随着玻璃样品中Eu浓度的增加，体积模量和杨氏模量呈现下降趋势，从255.49到253.10 GPa和368.20到366.50 GPa。与其他玻璃相比，EuGd4 玻璃的 LAC 值要小得多。玻璃中钆和铕化合物的存在增加了由于高原子序数元素而吸收辐射的能力。这是因为这些化合物的有效原子序数 (Z) 较高，增强了玻璃对中子和伽马射线的屏蔽能力，从而提高了辐射防护能力。
