Study of Li2O–B2O3–Dy2O3 glasses by impedance spectroscopy

Li2O–B2O3–Dy2O3 glasses have been synthesized by melt quench technique for different mol% Dy2O3. Investigation of these glasses by impedance spectroscopy reveals that DC conductivity is governed by mobile lithium ions. Electric modulus data has been analysed to study relaxation behaviour.

Summary:Li2O–B2O3–Dy2O3 glasses have been synthesized by melt quench technique for different mol% Dy2O3. Investigation of these glasses by impedance spectroscopy reveals that DC conductivity is governed by mobile lithium ions. Electric modulus data has been analysed to study relaxation behaviour. AC conduction mechanism is studied by using power law equation and it is observed that as the temperature decreases, frequency exponent (s) increases. Scaling by using AC conductivity and electric modulus shows good overlap of data on single master curve suggesting that conduction mechanism is independent of temperature. •Glasses were prepared by conventional melt quench technique.•Electrical properties were studied by Impedance spectroscopy.•AC conduction mechanism follows the Elliot’s correlated barrier hopping model.•The conduction mechanism in glasses is independent of temperature.
