摘要：

The carrier concentration and resistivity of electrochromic pyrolytic spray deposited tungsten trioxide films were measured. The resistivities of uncoloured films deposited at substrate temperatures between 200 and 400°C were found to be in the range 103-10-2 ω m and decreased by two to eight orders of magnitude after colouration. The colouration time was found to be dependent on thickness and deposition temperature of the oxide films. X-ray diffraction (XRD) studies of polycrystalline films prepared at temperatures higher than 350°C revealed structural changes during the electrochromic process. The XRD peaks for coloured films could be assigned to hydrogen tungsten bronze, and the structure of bleached films changed to the structure of the original uncoloured state. © 1990.
