Abstract This work aims to study the influence of gamma irradiation on some borophosphate glasses doped with PbO. Investigation of the structural changes and the optical properties of the studied glass network after successive gamma irradiation with doses of 500 Gy, 1 kGy, 2 kGy, and 5 kGy were done by UV–VIS and ATR-FTIR spectrometers, respectively. FTIR measurements confirmed that BO4 groups decrease and BO3 groups increase with the increase of γ-irradiation. UV–VIS absorption increased slightly with irradiation. The measurements of hardness before and after γ irradiation revealed that the hardness rose with the adding of PbO to glass. This model based on self-repairing for the structure-defects resulted from irradiation which not only creates defects but also induces reversible recovery of the defects. The outcomes reflected that the gamma-ray irradiation has a small influence on the network structure of the prepared glass. Consequently, it can be used in various applications as the nuclear fields.

γ辐照铅嵌硼磷酸锂玻璃的结构和光学性能

摘要 本工作旨在研究伽马辐照对一些掺杂PbO 的硼磷酸盐玻璃的影响。分别通过 UV-VIS 和 ATR-FTIR 光谱仪对所研究的玻璃网络在剂量为 500 Gy、1 kGy、2 kGy 和 5 kGy 的连续伽马辐射后的结构变化和光学性质进行了研究。FTIR 测量证实，随着γ-辐照的增加，BO4 基团减少，BO3 基团增加。UV-VIS 吸收随着辐照而略有增加。γ 辐照前后的硬度测量表明，随着玻璃中 PbO 的加入，硬度增加。该模型基于对由辐射引起的结构缺陷的自我修复，不仅产生缺陷，而且诱导缺陷的可逆恢复。结果表明伽马射线辐照对制备的玻璃的网络结构影响很小。因此，它可以用作核领域的各种应用。
