Abstract

X-ray absorption near edge structure spectroscopy has been used at the O K and Fe L_2,3 edges to investigate the electronic and atomic structure of (Fe₂O₃)_x(Na₂O) _0.30(SiO₂)_{0.70 - x} (x < 0.2) obtained by melt-quench technique. The Fe L_2,3 edge spectra show that the Fe atoms are in octahedral coordination. The O K edge spectra reveal no change in coordination of Fe and increased degree of hybridization between O 2p and Fe 3d orbitals with iron doping. It is estimated that about 10% Fe²⁺ and 90% Fe³⁺ are in these glasses by peak fitting analysis of Fe L ₃ edge. The ligand-field splitting of Fe 3d orbital is about 1.6 eV.
