Soft X-ray absorption spectroscopy of titanium dioxide nanopowders with cobalt impurities

The charge states of the cobalt ions in TiO 2 nanopowders with the anatase lattice are studied by soft X-ray absorption spectroscopy. It is found that, at a low cobalt impurity concentration (1.8 at %), the cobalt ions with an oxidation state 2+ are mainly located in the tetrahedral ( T d ) environm...
