An X-ray photoelectron spectroscopy study of yttria-stabilised zirconia (YSZ) single crystals is reported. It is shown that the shape and the binding energy positions of zirconium and yttrium core levels are independent of the yttria stoichiometry when the content of this oxide ranges from 12 to 24 mol.% of Y2O3. These results could indicate that the local crystallographic order around the Zr4+ and Y3+ ions does not depend on the Zr/Y ratio.

Abstract
An X-ray photoelectron spectroscopy study of yttria-stabilised zirconia (YSZ) single crystals is reported. It is shown that the shape and the binding energy positions of zirconium and yttrium core levels are independent of the yttria stoichiometry when the content of this oxide ranges from 12 to 24 mol.% of Y2O3. These results could indicate that the local crystallographic order around the Zr4+ and Y3+ ions does not depend on the Zr/Y ratio.File in questo prodotto:
