In recent years there has been a growing interest in the use of plasmonic nanostructures for color generation, a technology that dates back to ancient times. Plasmonic structural colors have several attractive features but once the structures are prepared the colors are normally fixed. Lately, several concepts have emerged for actively tuning the colors, which opens up for many new potential applications, the most obvious being novel color displays. In this review we summarize recent progress in active control of plasmonic colors and evaluate them with respect to performance criteria for color displays. It is suggested that actively controlled plasmonic colors are generally less interesting for emissive displays but could be useful for new types of electrochromic devices relying on ambient light (electronic paper). Furthermore, there are several other potential applications such as images to be revealed on demand and colorimetric sensors.

等离子体颜色的主动控制：新兴的显示技术

近年来，人们对使用等离子体纳米结构产生颜色越来越感兴趣，这项技术可以追溯到古代。等离子结构颜色有几个吸引人的特点，但一旦结构准备好，颜色通常是固定的。最近，出现了一些主动调整颜色的概念，这为许多新的潜在应用开辟了道路，最明显的是新颖的彩色显示器。在这篇综述中，我们总结了等离子体颜色主动控制的最新进展，并根据彩色显示器的性能标准对其进行了评估。有人建议，主动控制的等离子体颜色对于发光显示器通常不太有趣，但可能对依赖环境光（电子纸）的新型电致变色设备有用。此外，
