This study focuses on alkali oxide (lithium and sodium) glasses with an aim to explore suitable host for cerium ions which will enhance the optical properties like UV blocking efficiency. Conventional melt quench method was employed for making these glasses. FTIR results show conversion of BO₃ to BO₄ units and development of CeO₄ groups with addition of CeO₂. The increase in density values (2.10 to 2.67 g/cm³ for sodium glasses and 2.04 to 2.75 g/cm³ for Lithium glasses) and decrease in band gap values (3.16 to 2.40 eV for sodium glasses and 3.28 to 2.08 eV for Lithium glasses) in both glass systems confirm the modifier role of CeO₂. Hardness of lithium-based glasses (1366.91 Kg/mm²) at 4 mol% of CeO₂ is higher than the glasses containing sodium (1007.21 Kg/mm²). The obtained values of refractive index and transmittance show better suitability of CeO₂ incorporated lithium glasses in some optical applications.

这项研究集中在碱金属氧化物（锂和钠）玻璃上，目的是探索适合铈离子的基质，以增强光学特性，例如紫外线阻隔效率。使用常规的熔体淬火方法来制造这些玻璃。傅立叶红外光谱（FTIR）结果表明，加入CeO ₂后BO ₃转变为BO ₄单元并形成CeO ₄基。密度值的增加（钠玻璃为2.10至2.67 g / cm ³，锂玻璃为2.04至2.75 g / cm ³）和带隙值的减小（钠玻璃为3.16至2.40 eV，锂玻璃为3.28至2.08 eV ）在两种玻璃体系中均证实了CeO ₂的改性剂作用。CeO ₂为4摩尔％时，锂基玻璃（1366.91 Kg / mm ²）的硬度高于含钠的玻璃（1007.21 Kg / mm ²）。所获得的折射率和透射率值表明在某些光学应用中，掺入CeO _2的锂玻璃具有更好的适用性。
