Electrochromism in sol-gel deposited WO3 films containing TiO2 has been observed. The films are deposited by spin coating from peroxo-polytungstic acid and titanium isopropoxide precursors. The films were fabricated on quartz and SnO2:F coated glass substrates. Films were heat treated at 150 degrees C. Morphology of the films was examined by scanning electron microscopy, which indicated that the films were smooth and had a pore free surface.
