Sažetak
Optical spectroscopy was employed to study iron phosphate glasses of the general composition xFe2O3(100-x)P2O5(14<x<47mol%). Cation vibrational properties showed that iron is predominantly present as iron(II) in glasses of lower total iron content and as iron(III) in glasses of higher total iron content. In glasses containing 40 and 47 mol% Fe2O3 some of iron(III) ions changed from octahedral to tetrahedral coordination. Increasing iron content increased network disorder to the point where the structural changes occur, i.e. where iron cations changed their charge or coordination
