Gamma ray irradiation effects on non-doped lithium borate (LBO), lithium borosilicate (LBS), and cerium (Ce)-doped lithium borosilicate glasses (LBS) are investigated. All non-doped lithium borosilicate glasses exhibit gamma ray irradiation damage in the form of red shifting of the optical absorption edge, appearance of an absorption peak between 500 nm and 600 nm, and the overall increase of absorption in the visible wavelength region. The absorption peak underwent a red shift as the optical basicity of the glass samples increased. Further investigation of the behavior of Ce in the form of CeO₂ and CeF₃ in LBS glass before and after gamma ray irradiation reveal that the addition of Ce improved the overall transparency of LBS after irradiation, whereby the formerly observed absorption peak disappeared with an optimum Ce content between 1 mol% and 3 mol%. Photoluminescence (PL) spectroscopy shows an increase in the PL intensity of CeO₂-LBS after gamma ray irradiation but a decrease for CeF₃-LBS, alluding to the conversion of Ce³⁺ to Ce⁴⁺.

研究了γ射线辐照对未掺杂的硼酸锂（LBO），硼硅酸锂（LBS）和铈（Ce）掺杂的硼硅酸锂玻璃（LBS）的影响。所有未掺杂的硼硅酸锂玻璃均表现为伽玛射线辐照损坏，其形式为光学吸收边缘发生红移，出现在500 nm至600 nm之间的吸收峰以及在可见波长范围内的吸收总量增加。随着玻璃样品的光学碱度增加，吸收峰发生红移。对CeO ₂和CeF ₃形式的Ce行为的进一步研究在γ射线辐照之前和之后的LBS玻璃中的X射线衍射表明，添加Ce改善了辐照后LBS的整体透明性，从而以1mol％至3mol％的最佳Ce含量消失了先前观察到的吸收峰。光致发光（PL）光谱显示，在γ射线辐照后，CeO ₂ -LBS的PL强度增加，但CeF ₃ -LBS的降低，这暗示了Ce ³⁺向Ce ⁴⁺的转化。
