Abstract
ZnF2–P2O5–TeO2 glasses containing different concentrations of MnO (ranging from 0 to 0.6%) were prepared. A number of studies, viz. differential thermal analysis, optical absorption, thermo luminescence, infrared spectra, magnetic susceptibility, elastic properties (Young's modulus Y, shear modulus n and micro hardness H) and dielectric properties (constant ε, loss tanδ, a.c. conductivity σac over a range of frequency and temperature and dielectric breakdown strength), of these glasses were carried out as a function of manganese ion concentration. The analysis of the results indicate manganese ions mostly exist in Mn2+ state in these glasses when the concentration of MnO≤0.4% and above this concentration manganese ions predominantly exist in Mn3+ state; from this analysis an attempt is made to identify the role of these ions on the stability of glass network.
