VANADIUM-OXIDES AND QUANTITATIVE EXPLOITATION OF XPS DATA

The potential of XPS as analytical tool has been used in this work to obtain important physical information relative to some vanadium oxides such as: V2O5, V6O13, VO2 and V2O3. Respect to the shake-up satellite associated with the oxygen Ols peak has been studied with some attent ion. We have presented some arguments that support the existence of a shake-up structure associated with the vanadium peak V2p(3/2) in V2O5. It isalso shown that the N-O/N-V ratio can not be used reliably to di fferentiate between different vanadium oxidation states.
