On the Electron Paramagnetic Resonance Studies in Mixed Alkali Borate Glasses
Abstract
Mixed alkali effect in oxide based glasses is one of the current research activity and studies on the behavior of spectroscopic parameters in these systems are quite important to understand the basic nature of this phenomenon. EPR studies of mixed alkali glasses Li2O-K2O-ZnO-B2O3 doped with Fe3+ and Mn2+ were carried out at room temperature. The EPR spectra show typical resonances of d5 system (Fe3+ and Mn2+) in all the measured glass specimens. Evaluated hyperfine constant, number of paramagnetic centers and paramagnetic susceptibility values show deviation from the linearity with the progressive substitution of the Li ion with K in glass network.
