Research progress of inorganic all-solid-state electrochromic devices

电致变色是一种在外加电场下材料光学属性可变的现象。本文围绕全固态电致变色器件,阐述了器件中每一层的结构、可选材料、性能等,并根据全固态电致变色器件近期的研究进展,总结了两种全固态器件的典型结构,详细介绍了两类器件结构的结构特点、制备方法和电致变色性能,并展望了未来全固态电致变色器件的发展方向。

The optical properties of electrochromic materials can be reversibly changed by the insertion/extraction of ions and electrons depending on the applied external potential.In this paper,based on all-solid-state electrochromic devices(ECDs),the concept,function,and optional materials of each layer of the devices are introduced.According to the recent progress,two kinds of all-solid-state ECDs are summarized,and the structure characteristics,preparation methods,and electrochromic properties are introduced in detail.Finally,the development direction of all-solid-state ECDs in the future is prospected.
