Abstract
In the present work, a study of the temperature dependence of the d.c. electrical conductivity and conduction activation for a series of MoO3-P2O3 glass systems has been carried out. The conductivity measurements of the unirradiated glass specimens proved to be mainly dependent on both temperature and transition metal ion content in the glass matrix. The results of the present investigation have shown that the conduction mechanism would be due to the electron exchange between the low and high valency states of the MoO3 oxide (Mo" and Mo6+). The radiation-induced conductivity of the glass system studied, produced by gamma rays, has also been measured experimentally. The d.c. electrical conductivity has proved to be dose dependent, which showed a decrease with increasing γ-dose. The results reflect some evidence of theγ-ray dosimetric potential of the glass specimens studied.
