        Tungsten oxide film synthesis by spray pyrolysis of peroxotungstic acid and its electrochromic characterization

        Chang-Yeoul Kim,Seong-Geun Choa,Seok Park,최덕균 한양대학교 세라믹연구소 2009 Journal of Ceramic Processing Research Vol.10 No.6

        Peroxotungstic acid precursor solution was sprayed on indium-doped tin oxide (ITO) glass substrates to synthesize amorphous and crystalline phase tungsten oxide thin films by changing heating temperature. We could synthesize the amorphous phase at below 400℃ and the monoclinic crystalline tungsten oxide at above 400℃. Electrochemical and in-situ optical transmittance analysis showed that amorphous phase tungsten oxide at 250℃ had a good electrochromic property with a large optical transmittance change between its bleached and colored states. The coloration mechanisms are due to polaron generation by inserting ions and electrons to change W+6 state to W+5 or W+4 state.
