Novel glass samples with the composition 75TeO-5TaO-15NbO-5x (where x = ZnO, MgO, TiO, or NaO) in mole percent were prepared. The physical, optical, and gamma radiation shielding properties of the glass samples were studied over a wide energy spectrum ranging between 0.015 and 20 MeV. The glasses' UV-vis spectra were utilized to evaluate the optical energy gap and refractive index. Glass samples had a refractive index ranging from 2.2005 to 2.0967. The results showed that the sample doped with zinc oxide (ZnO) recorded the highest density (), molar polarizability (), molar refraction (), refractive index (n), and third-order nonlinear optical susceptibility (χ) and the lowest optical energy gap (E) among the samples under investigation. When comparing the current glass system with various standard glass shielding materials, the prepared glass system showed superior shielding performance at energies ranging between 40 and 85 keV. These findings indicate that the prepared glass systems can be used in diagnostic X-rays, especially in dental applications.
制备了摩尔百分比组成为75TeO-5TaO-15NbO-5x(其中x = ZnO、MgO、TiO或NaO)的新型玻璃样品。在0.015至20 MeV的宽能谱范围内研究了玻璃样品的物理、光学和γ辐射屏蔽性能。利用玻璃的紫外-可见光谱评估光学能隙和折射率。玻璃样品的折射率范围为2.2005至2.0967。结果表明,在所研究的样品中,掺杂氧化锌(ZnO)的样品具有最高的密度()、摩尔极化率()、摩尔折射度()、折射率(n)和三阶非线性光学 susceptibility(χ),以及最低的光学能隙(E)。当将当前玻璃系统与各种标准玻璃屏蔽材料进行比较时,所制备的玻璃系统在40至85 keV的能量范围内表现出优异的屏蔽性能。这些发现表明,所制备的玻璃系统可用于诊断X射线,特别是在牙科应用中。
