Transition metal oxides have drawn tremendous interest due to their unique physical and chemical properties. As one of the most promising electrochromic (EC) materials, tungsten trioxide (WO) has attracted great attention due to its exceptional EC characteristics. This review summarizes the background and general concept of EC devices, and key criteria for evaluation of WO-based EC materials. Special focus is placed on preparation techniques and performance enhancement of WO EC films. Specifically, four methods - nanostructuring, regulating crystallinity, fabricating hybrid films, and preparing multilayer composite structures - have been developed to enhance the EC performance of WO films. Finally, we offer some important recommendations and perspectives on potential research directions for further study.
过渡金属氧化物由于其独特的物理和化学性质而引起了极大的关注。作为最有前途的电致变色（EC）材料之一，三氧化钨（WO）因其出色的 EC 特性而引起了极大的关注。本综述总结了 EC 器件的背景和一般概念，以及评估基于 WO 的 EC 材料的关键标准。特别关注 WO 电致变色薄膜的制备技术和性能增强。具体而言，已经开发了四种方法 - 纳米结构化、调节结晶度、制造混合膜和制备多层复合结构 - 以增强 WO 薄膜的 EC 性能。最后，我们对进一步研究的潜在研究方向提出了一些重要的建议和观点。
