X-ray absorption measurements at the Ce L-3 L-1 and Ti K-edges have been done to study local structure and electronic properties of CeO2-TiO2 thin films produced by reactive d.c. magnetron sputtering. The local environment around titanium and cerium ions can be described as pyramid-like and cube-like polyhedral respectively, and the films are amorphous (correlation radius about 10 Angstrom). The analysis of Ce L-3-edge XANES data has shown that the position of the Ce 4f(1)5d and 4f(0)5d states progressively shift towards lower energies with decreasing cerium dioxide content in the thin films.
