Europium-doped magnesium–zinc–sulfophosphate glasses of molar composition (65 − x) P₂O₅–20MgO–15ZnSO₄–xEu₂O₃ (x = 0.0, 0.5, 1.0, 1.5 and 2.0) were prepared via melt-quenching method. The synthesized glasses were characterized at room temperature to determine the relationship between Racah and mechanical properties. The FTIR spectra of glasses in the range of 4000–400 cm⁻¹ revealed the presence of characteristic functional groups. The Young’s, shear and bulk moduli of glasses were observed to enhance with the increase in Eu³⁺ contents. The ratio increased from 0.710 to 0.747 which confirms the increase in the degree of centrality of the glasses. Racah parameters evaluated from first three major absorption bands were reduced from 72.3906 to 60.1111 cm⁻¹ with the increase in Europium contents, thus signifying the weakening in f–f electrons repulsion. Crystal field parameters decrease from 42.2445 to 35.2397 cm⁻¹ denoting strong covalent character of ligand bond of the synthesized glass system. The synthesized glasses have potential for the development of hard surface engineering.

摩尔熔融组成（65 − x）P ₂ O ₅ –20MgO–15ZnSO ₄ – x Eu ₂ O ₃（x = 0.0、0.5、1.0、1.5和2.0）的magnesium掺杂镁-锌-硫代磷酸盐玻璃 是通过熔体制备的。淬火法。在室温下对合成玻璃进行表征，以确定拉卡与机械性能之间的关系。在4000–400 cm ^-1范围内，玻璃的FTIR光谱表明存在特征性官能团。随着Eu ³⁺的增加，玻璃的杨氏模量，剪切模量和体积模量增加。内容。该比率从0.710增加到0.747，证实了眼镜的中心度的增加。随着Euro含量的增加，从前三个主要吸收带评估的Racah参数从72.3906减小到60.1111 cm ^-1，这表明f-f电子斥力减弱。晶体场参数从42.2445降低到35.2397 cm ^-1，表明合成玻璃系统的配体键具有很强的共价特性。合成玻璃具有开发硬表面工程的潜力。
