EPR Study of some lead-phosphate glasses

The xFe2O3(1-x)[2P205 PbO] glass system with 0.5.x550 mol% was prepared and investigated by means of EPR spectroscopy in order to evidence the structural changes induced by the iron ions in different ratios. The isolated Fe3+ ions are situated in sites of distorted octahedral symmetries (rhombic or...

Zusammenfassung:The xFe2O3(1-x)[2P205 PbO] glass system with 0.5.x550 mol% was prepared and investigated by means of EPR spectroscopy in order to evidence the structural changes induced by the iron ions in different ratios. The isolated Fe3+ ions are situated in sites of distorted octahedral symmetries (rhombic or tetragonal). The dipolar and superexchange interactions were also revealed among iron ions in function of Fe2O3 content of the samples.
