摘要

本研究利用公式[(TeO2)70(B2O3)30]，探讨了 Gd2O3 对锌硼玻璃的弹性和辐射屏蔽特性的影响。采用熔融淬火技术制作了含有 1-5% mol% Gd2O3 的玻璃样品。XRD 验证了它们的非晶性质，红外光谱揭示了 TeO3、TeO4、BO3 和 BO4 振荡基团的存在。纵向和剪切超声波速度范围分别为 3908-4076 m/s 和 2222-2277 m/s，表明了结构的改变。随着 Gd2O3 含量的增加，玻璃的刚性得到改善，体积弹性模量（45 GPa）、纵向弹性模量（80 GPa）、剪切弹性模量（25 GPa）和杨氏模量（60 GPa）都有大幅提高。根据 WinXcom 的测量，Gd2O3 的浓度越高，质量衰减系数（μρ）就越大，从而增强了伽马射线屏蔽效果。0.662 MeV 时的半值层（HVL）和平均自由路径（MFP）随着 Gd2O3 的增加而一致下降。含 5 摩尔 Gd2O3 的玻璃具有最大密度和最佳伽马射线屏蔽性能。这些结果表明，Gd2O3 能够影响玻璃网络的弹性和辐射屏蔽效率，因此可用于需要更高硬度和更好辐射防护的应用领域。

Elastic and radiation shielding properties of zinc borotellurite glass systems: The impact of gadolinium oxide

Using the formula [(TeO₂)₇₀(B₂O₃)₃₀], this study examines the impact of Gd₂O₃ on the elasticity and radiation shielding characteristics of zinc borotellurite glass. Glass samples containing 1–5% mol% Gd₂O₃ were created by employing the melt quench technique. XRD verified that they are amorphous in nature, and the existence of TeO₃, TeO₄, BO₃, and BO₄ vibrational groups was revealed by infrared spectra. The structural alterations were shown by the range of longitudinal and shear ultrasonic velocities, which were 3908–4076 m/s and 2222–2277 m/s, respectively. The glass's rigidity was improved by the large rise in elastic moduli, such as bulk (45 GPa), longitudinal (80 GPa), shear (25 GPa), and Young's moduli (60 GPa), with a higher Gd₂O₃ content. Higher concentrations of Gd₂O₃ resulted in a rise in the mass attenuation coefficient (μ_ρ), as measured by WinXcom, which enhanced gamma-ray shielding. The half-value layer (HVL) and mean free path (MFP) at 0.662 MeV decreased with increasing Gd₂O₃ in a consistent manner. The maximum density and optimum gamma-ray shielding performance were found in the glass containing 5 mol% Gd₂O₃. These results show Gd₂O₃ for applications needing greater rigidity and better radiation protection by demonstrating how it affects the elastic and radiation-shielding efficiency of the glass network.
