The development of electrochromic (EC) materials has paved the way for a wide range of devices, such as smart windows, color displays, optical filters, wearable camouflages, among others. However, the advancement of electrochromism faces a significant hurdle due to its poor stability and limited color options. This lack of stability is primarily attributed to the substantial alteration in the dielectric properties of EC materials during cycling. Consequently, the design of advanced plasmonic materials is a key strategy to achieve a stable EC device. In this review, we provide an overview of the current state-of-the-art designs of plasmonic-based EC materials and devices. We discuss their working principles, techniques for structure/morphology engineering, doping methods, and crystal phase design. Furthermore, we explore the integration of plasmonic materials with other EC materials to create advanced EC devices. Finally, we outline the challenges that need to be addressed and present an outlook on the development of high-performance EC devices.
电致变色（EC）材料的发展为众多设备铺平了道路，如智能窗户、彩色显示器、光学滤波器、可穿戴伪装等等。然而，由于其稳定性差和颜色选择有限，电致变色技术的发展面临着重大障碍。这种稳定性的缺乏主要归因于EC材料在循环过程中介电性能的大幅变化。因此，设计先进的等离子体材料是实现稳定EC器件的关键策略。在这篇综述中，我们概述了基于等离子体的EC材料和器件的当前最新设计。我们讨论了它们的工作原理、结构/形态工程技术、掺杂方法和晶相设计。此外，我们还探索了等离子体材料与其他EC材料的集成，以制造先进的EC器件。最后，我们概述了需要解决的挑战，并对高性能EC器件的发展进行了展望。
