The structural role of chromium ions on the improvement of insulating character of ZnO–ZnF2–B2O3 glass system by means of dielectric, spectroscopic and magnetic properties

The role of chromium ions on the improvement of insulating character of ZnO–ZnF2–B2O3 glass system by means of dielectric properties coupled with spectroscopic and magnetic properties has been carried out. The analysis of the results indicate that there is a substantial enhancement of insulating strength of ZnO–ZnF2–B2O3 glasses if Cr2O3 is present around 1.0 mol% in the glass matrix.
