Electronic Structures of Iron in Oxide Glasses via 1s3p Resonant Inelastic X-ray Scattering.

ABSTRACT: Electronic structures of iron in glasses are essential for unraveling the effect of transition metals on amorphous networks and controlling the electro-optical and transport properties of advanced glasses and amorphous energy-storing materials. The electronic configurations around iron in glasses, however, remain not well understood due to the structural disorders arising from multiple iron species with distinct valence, coordination, and spin states. Here, the first 1s3p resonant inelastic X-ray scattering (RIXS) for oxide glasses identifies hidden electronic configurations for Fe²⁺ and Fe³⁺ in amorphous networks. The results allow us to quantify the composition-induced evolution of oxygen ligand-field interactions of high-spin Fe 3d states with varying valence and c
