Abstract

Abstract ZnO–Sb 2O 3–B 2O 3 glasses containing different concentrations of MnO ranging from 0 to 1.0 mol% were prepared. A number of studies, viz. optical absorption, infrared and ESR spectra and magnetic susceptibility, were carried out as a function of manganese ion concentration. The analysis of the results indicate that manganese ions mostly exist in Mn 2+ state in these glasses when the concentration of MnO≤0.6 mol% and above this concentration, these ions seem to exist in Mn 3+ state in the glass network.
