Abstract
⺠Cobalt in the cobalt doped TiO2 thin films was mainly in Co2+ oxidation state. ⺠CoTiO3 was discovered in the cobalt doped TiO2 films after annealing above 650 °C. ⺠During annealing cobalt compounds segregate to the surface of samples. ⺠EDX analysis showed that “islands” of cobalt compounds are formed in the sample. ⺠Cobalt doping red-shifted the fundamental absorption edge compared to virgin titania.
