Titanium dioxide films (TiO 2 ) doped cobalt transition metal were prepared on titanium metal by water spray pyrolysis technique. Micro-morphology, crystalline structure, chemical composition and binding state of sample groups were evaluated using field emission scanning microscope(FE-SEM), X-ray diffractometer(XRD), Raman spectrometer, X-ray photoelectron spectrometer(XPS). TiO 2 films of rutile structure were predominately formed on all sample groups and Ti 2 O 3 oxide was coexisted on the surface of cobalt doped-sample groups. The optical absorption peaks measured by using UV-VIS-NIR spectrophotometer were observed at specific wavelength region in sample groups doped cobalt ion. This result could be analyzed by introducing crystal field theory.

Keywords:Titanium dioxide;cobalt ion;spray pyrolysis;photocatalyst;optical absorption
