It is the first report of study on the vacuum--evaporated electrochromic WO3 filmusing EXAFS (Extended X-ray Absorption of Fine Structure) .During evaporation, the longrange of WO3 powder-the precursor was vigorously ...
The amorphous V 2O 5 films prepared by vacuum evaporation are unstable and easily dissolved by electrolyte during the electrochromic process, so unfit to make electrochromic materials. We found that the annealed films...
