This work is aimed to shed light on the dielectric behavior of CuO containing glasses, since
no publications concerning this issue have been presented before. Different glasses
in the binary Na2O-B2O3 systemwere
prepared by melt annealing technique. XRD spectra have shown that the amorphous
structure is dominant in all glasses containing mixed concentrations from CuO and
Na2O. The crystalline phases appeared only in glass free from Na2O.
The dielectric spectroscopy is applied to shed some light on the conduction mechanisms
in terms of changing both the dielectric constant and the electrical modulus of
the investigated glasses. The ac conductivity increases with increasing frequency
and decreases with increasing CuO concentration. Both the dielectric constant and
dissipation loss is decreased with increasing frequency. Correlated barrier hopping (CBH) is
considered an appropriate conduction mechanism results from the increase of frequency.
