Abstract

This study focused on synthesizing glasses with the formula (70-x-y)B₂O₃-20BaO-10TiO₂-xZnO-yPbO (where x = y = 5, 10, 15, and 20 mol %) using the melt-quenching approach and examined the impact of ZnO and PbO substitution on the mechanical, optical, and radiation shielding properties of these glasses. The mechanical moduli and micro-hardness decreased with higher ZnO and PbO concentrations, indicating reduced rigidity and elasticity. Optical analyses demonstrated that as ZnO and PbO contents increased, the absorption edge shifted to longer wavelengths, and the optical band gap (E_g) decreased. Furthermore, Urbach energy (E_U) values increased from 0.212 to 0.431 eV, indicating a higher degree of structural disorder. Radiation shielding studies revealed that glasses with higher concentrations of ZnO and PbO demonstrated enhanced shielding capabilities. Among the glasses prepared, the sample with the composition 30B₂O₃ + 20BaO + 10TiO₂ + 20ZnO + 20PbO exhibited the best performance, characterized by a high mass attenuation coefficient (MAC) and linear attenuation coefficient (LAC).

定制玻璃特性：揭示用于高级辐射防护的硼酸钛钡玻璃中氧化铅和氧化锌的影响

本研究的重点是采用熔淬法合成式为（70-x-y）B2O3-20BaO-10TiO2-xZnO-yPbO（其中 x = y = 5、10、15 和 20 mol %）的玻璃，并考察 ZnO 和 PbO 替代对这些玻璃的机械、光学和辐射屏蔽性能的影响。氧化锌和氧化铅浓度越高，机械模量和微硬度越低，表明刚性和弹性降低。光学分析表明，随着氧化锌和氧化铅含量的增加，吸收边缘向更长的波长移动，光带隙（Eg）减小。此外，厄巴赫能（EU）值从 0.212 eV 增加到 0.431 eV，表明结构紊乱程度更高。辐射屏蔽研究表明，氧化锌和氧化铅浓度较高的玻璃具有更强的屏蔽能力。在制备的玻璃中，成分为 30B2O3 + 20BaO + 10TiO2 + 20ZnO + 20PbO 的样品性能最佳，具有较高的质量衰减系数（MAC）和线性衰减系数（LAC）。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
