【 摘 要 】

In this paper, we report the conductivity measurements of transition metal doped mixed alkali bismuth borate glasses prepared by melt quenching technique. The AC conductivity was studied in the frequency range 100Hz-1MHz.At room temperature the AC conductivity increased with the increase in frequency. For all the glass samples, dielectric constant and dielectric loss decreased with increase in the frequency. The DC conductivity measurement has been carried out by two probe method in the temperature range 403 to 573K.The DC conductivity values for all the prepared glass samples was observed to lie in the range 10-8 - 10-6 S m-1. Activation energy values were calculated using the conductivity data. The conductivity was found to increase with the increasing temperature exhibiting the semiconducting nature of the prepared glasses.
