Impedance spectroscopic characterization of Sm2O3 containing lithium borate glasses

• Lithium borate glasses containing Sm2O3 were prepared by conventional melt quench technique.
• Conductivity of glasses decreases due to decrease in mobility of lithium ions.
• Scaling indicates that the conduction mechanism is independent of temperature.

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.
