【 摘 要 】

Tungsten trioxide (WO3) thin films are of great interest as counter electrodes in electrochromic (EC) devices such as ‘smart window’ for energy-efficient buildings. Uniform WO3 nanoplates filmed as EC working electrodes were fabricated on seed-free fluorine-tin-oxide (FTO) coated glass via a facile and addictive agent-free hydrothermal process. The WO3 nanoplates were characterised by scanning electron microscopy and the X-ray photoelectron spectroscopy. The morphological analysis of the film showed that the WO3 nanoplates lying on the FTO glass uniformly. Fourier transform infrared spectroscopy was applied to study the vibrational information of the sample. Furthermore, uniform WO3 nanoplates exhibit well performance of EC properties. Owing to the highly two-dimensional nanostructure, a fast switching speed of 12 and 3 s for colouration and bleaching are achieved for WO3 film. These properties of the WO3 nanoplates film endow its promising practical applications in smart windows.
