27.5 Li2O-(72.5-X) B2O3-X Sm2O3 (X=0.5, 1, 1.5 and 2) were prepared by conventional melt quench technique. Impedance spectroscopy (IS) is used to study the electrical properties of these prepared glasses. Modulus formalism is introduced to study relaxation behaviour of these glasses. Scaling model shows the good overlap of data on single master curve which suggests that conduction mechanism in these glasses is compositional dependent. Variation of dielectric constant and dielectric loss with the addition of Sm2O3 and frequency are discussed here.
采用传统熔体淬冷技术制备了27.5Li2O-(72.5-X)B2O3-X Sm2O3（X = 0.5、1、1.5和2）。利用阻抗谱（IS）研究这些制备玻璃的电学性质。引入模量形式来研究这些玻璃的弛豫行为。标度模型表明数据在单一主曲线上有良好的重叠，这表明这些玻璃中的传导机制与成分有关。本文讨论了添加Sm2O3和频率时介电常数和介电损耗的变化。
