Abstract
A series of zinc phosphate glass doped with cobalt
Na2Zn(1 − x)CoxP2O7 (x = 0, 1, 2 and 5 mol%) was synthesized.
These glasses were characterized by both infrared and
large broadband dielectric spectroscopy. Infrared spectra indicate
the increase of Zn/Co ratio creates defect in phosphate
network due to the depolymeration of phosphate anions. The
dc conductivity increases and activation energy decreases with
the amount of cobalt ions in the glass network. The impedance
measurements reveal that the total conductivity follows
Jonscher’s power law. The dielectric constant and dielectric
loss increased with the temperature and decreased with the
frequency whatever the cobalt proportion.
