J. Purans et al., X-ray absorption study of the electronic structure of tungsten and molybdenum oxides on the OK-edge, ELECTR ACT, 46(13-14), 2001, pp. 1973-1976
Magnetron sputtered amorphous thin films a-WO3, a-MoO3 and doped a-WO3:Ir h
ave been studied by X-ray absorption spectroscopy on the oxygen K-edge in c
omparison with crystalline oxides as monoclinic m-WO3, orthorhombic alpha -
MoO3, cubic Na0.6WO3, layered-type hexagonal h-WO3 and WO3.H2O, having Vari
able electronic and atomic structure. The changes in the XANES ranging 10-1
5 eV above the absorption edge are interpreted based on the known band-stru
cture calculations. The high-energy features are related to the multiple-sc
attering processes (EXAFS) at the nearest atoms. (C) 2001 Elsevier Science
