Using the traditional melt quenching process, the glass series of CdO-() ZnO-35PbO-60SiO, where x = 1–5 mol%, were created. The X-ray diffraction method was utilized to investigate the non-crystallinity of the glasses that were created. The densities of the fabricated glasses increased from 5.91 to 6.655 g/cm³. Electronegativity (ΔX), bond density (nb), and field strength (F) were calculated. ΔX decreased while nb and F increased with the supply of Cd ions. The optical characteristics E, n, α, ε, χ, n2, M, T and more have been investigated. We found that a change in cadmium concentration in the fabricated system influenced all the optical parameters. The mechanical properties, including elastic moduli, have been investigated alongside ultrasonic velocity measurements. The experimental results demonstrated a strong dependence of calculated parameters on increasing CdO concentration. The observation indicates an increase in the elastic moduli with the increasing CdO concentration. Radiation shielding factors were estimated using EpiXS program. μ, HVL, MFP, Z, N, EBF and EABF for gamma energy between 15 and 15,000 KeV have been investigated. The results indicate that these parameters are affected by the introduction of CdO content into the glass network. The sample ZPSCd5 exhibits the highest radiation shielding parameters among the studied glass samples.

揭示镉掺杂对锌铅硅酸盐玻璃结构、光学、机械和γ射线屏蔽特性的协同效应

使用传统的熔融淬火工艺,创建了 CdO-()ZnO-35PbO-60SiO 玻璃系列,其中 x = 1–5 mol%。 X 射线衍射方法用于研究所制造的玻璃的非结晶性。制成的玻璃的密度从 5.91 克/立方厘米增加到 6.655 克/立方厘米。计算电负性 (ΔX)、键密度 (nb) 和场强 (F)。随着Cd离子的供应,ΔX减少,而nb和F增加。研究了光学特性 E、n、α、ε、χ、n2、M、T 等。我们发现所制造的系统中镉浓度的变化会影响所有光学参数。包括弹性模量在内的机械性能已与超声波速度测量一起进行了研究。实验结果表明计算参数对 CdO 浓度的增加有很强的依赖性。观察结果表明弹性模量随着 CdO 浓度的增加而增加。使用 EpiXS 程序估算辐射屏蔽系数。已研究了 15 至 15,000 KeV 之间伽玛能量的 μ、HVL、MFP、Z、N、EBF 和 EABF。结果表明,这些参数受到玻璃网络中引入的 CdO 含量的影响。在所研究的玻璃样品中,ZPSCd5 样品表现出最高的辐射屏蔽参数。
