摘要：

The ac conductivity of cuprate glasses based on the unconventional network former PbO is reported in the frequency range 10(2)-10(5) Hz and in the temperature range 80-450 K. Analysis of the conductivity data has been made in the light of different existing theoretical models. It is observed that, among them, the correlated barrier hopping model can best explain the conductivity and frequency exponent data. The values of the different parameters obtained from this model are reasonable. The high values of the dielectric constant observed in this system are attributed to the high polarizability of the unconventional network former PbO.
