Abstract [en]

Resonant X-ray emission spectroscopy (RXES) was applied to probe the electronic states above Fermi level for Cr-doped anatase TiO2. The results reveal doping-induced electronic band on low energy side of unoccupied electronic states. The experimental RXES data in combination with theoretical simulations allowed distinguishing electronic state changes on both, d-localized and d-delocalized orbitals of Cr-doped anatase TiO2. The detailed information on unoccupied electronic states is crucial in order to correlate enhanced light absorption properties with catalytic activity of the material.
