Abstract
In order to investigate the effects of Na ions to the hyperfine parame ters of Fe3+ and Fe2+ ions in xNa2O-(40-x)Fe2O3-60P2O5 glasses, the co mpositional dependencies of isomer shift (IS) and quadrupole splitting (QS) for Fe3+ and Fe2+ ions were measured by Mossbauer spectroscopy. It was found that IS and QS of Fe3+ ions were influenced even at a sma ll Na2O content, but those of Fe2+ ions were influenced at a Na2O cont ent of larger than 20 mol.%. The latter was related to the formation o f nonbridging oxygen (NBO).
