Influence of Cd substitution and temperature on dielectric properties of SnO2

The temperature dependence of dielectric properties of Cd-doped SnO2 nanoparticles has been carried out successfully in the temperature range 30 to 300 °C at specific frequencies. The dielectric constant of pure and Cd-doped SnO2 sample at selected frequency increases with increasing temperature. The loss tangent of pure and doped materials has also been examined. Ac conductivity of Cd incorporated SnO2 samples increases with increasing temperature. Further, the activation energies at different frequencies for all samples have been estimated.
