X-ray Spectroscopy of Inorganic Materials

By P.S. Miedema

Abstract

X-ray spectroscopies have been applied on different inorganic materials with a main focus on 3d-metal materials and iron compounds in particular. Different theoretical treatments of x-ray absorption spectroscopy (XAS) are compared with each other and with experimental data. XAS calculations have been performed for iron to study the XAS shapes of different spin states of iron as well as the resonant inelastic x-ray scattering. XAS has been applied in-situ to study changes in 3d-metal materials in different gas environments and based on the experimental and calculations differences in the oxygen adsorption on the different studied 3d-metal compounds were observed. X-ray photoemission spectroscopy (XPS) confirmed these results. Hard X-ray XPS was applied on iron oxide to show the abilities of Fe 1s XPS to obtain the important charge transfer parameters. Finally X-ray Raman spectroscopy (XRS) has been applied to the hydrogen storage material LiBH4. XRS may show similar spectra as XAS and it is necessary if the elements Li and B have to be studied in-situ
