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.
近年来，人们对使用等离子体纳米结构来产生颜色的兴趣日益浓厚，这项技术可追溯到古代。等离子体结构色具有几个吸引人的特性，但一旦制备好结构，颜色通常就固定了。最近，出现了几种用于主动调节颜色的概念，这为许多新的潜在应用开辟了道路，最明显的就是新型彩色显示器。在这篇综述中，我们总结了等离子体颜色主动控制方面的最新进展，并根据彩色显示器的性能标准对其进行评估。结果表明，主动控制的等离子体颜色对于发光显示器来说通常不太有吸引力，但对于依赖环境光的新型电致变色器件（电子纸）可能会有用。此外，还有其他一些潜在应用，比如按需显示的图像和比色传感器。
