Abstract
X-ray photoelectron spectroscopy was used to study the chemical composition and valence states of the metal ions in vanadium-yttrium. hydrate. The bin ding energies, FWHM and shape of the main XPS peaks were analyzed. The conc entration ratio of tetra- and pentavalent vanadium ions C=V4+ /(V4+ +V5+), which is an important parameter, deciding the electronic part of total cond uctivity, was determined before (C=0.14) and after heating at 720 K (C=0.28 ).
