三氧化钨（WO3）薄膜作为电致变色（EC）器件如节能建筑物的“智能窗”中的对电极引起了极大的兴趣。采用一种简单、无添加剂的水热法，在无晶种的氟锡氧化物（FTO）涂层玻璃上制备了均匀的WO3纳米片作为电化学工作电极。通过扫描电子显微镜和X射线光电子能谱对WO3纳米片进行了表征。薄膜的形貌分析表明，WO3纳米片均匀地分布在FTO玻璃上。用傅里叶变换红外光谱研究了样品的振动信息。此外，均匀的WO3纳米片表现出良好的电化学性能。由于高度二维的纳米结构，实现了12和3秒的快速切换速度的着色和漂白的WO3薄膜。WO3纳米片薄膜的这些特性使其在智能窗领域具有广阔的应用前景。
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.
