Electronic structure of ytterbium-doped strontium fluoroapatite: Photoemission and photoabsorption investigation

X-ray photoemission and x-ray photoabsorption were used to study the composition and the electronic structure of ytterbium-doped strontium fluoroapatite (Yb:S-FAP). High resolution photoemission measurements on the valence band electronic structure and Sr 3d, P 2p and 2s, Yb 4d and 4p, F 1s, and O 1...

Zusammenfassung:X-ray photoemission and x-ray photoabsorption were used to study the composition and the electronic structure of ytterbium-doped strontium fluoroapatite (Yb:S-FAP). High resolution photoemission measurements on the valence band electronic structure and Sr 3d, P 2p and 2s, Yb 4d and 4p, F 1s, and O 1s core lines were used to evaluate the surface and near surface chemistry of this fluoroapatite. Element specific density of unoccupied electronic states in Yb:S-FAP were probed by x-ray absorption spectroscopy at the Yb 4d (N4,5 edge), Sr 3d (M4,5 edge), P 2p (L2,3 edge), F 1s, and O 1s (K edges) absorption edges. These results provide measurements of the electronic structure and surface chemistry of this material.
