Plasmonic color filtering and color printing have attracted considerable attention in recent years due to their supreme performance in display and imaging technologies. Although various color‐related devices are designed, so far very few studies have touched the topic of dynamic color generation. In this article, dynamic color generation is demonstrated by integrating plasmonic nanostructures with vanadium dioxide based on its tunable optical properties through insulator–metal transition. Periodic arrays of silver nanodisks on a vanadium dioxide film are fabricated to realize different colors, relying on the excitation of localized and propagating surface plasmons, and Wood's anomaly. By tuning spatial periodicity of the arrays and diameter of the silver nanodisks, various colors can be achieved across the entire visible spectrum. Further, using insulator–metal transition of vanadium dioxide, the colors can be actively tuned by varying temperature. The approach of dynamic color generation based on the phase transition of vanadium dioxide can easily realize diverse color patterns, which makes it beneficial for display and imaging technology with distinct advantages of multifunctionality, flexibility, and high efficiency.

基于二氧化钒相变的动态等离子体彩色生成

由于等离子滤色和彩色印刷在显示和成像技术中的卓越性能，近年来受到了相当大的关注。尽管设计了各种与颜色相关的设备，但到目前为止，很少有研究涉及动态颜色生成的主题。在本文中，通过将等离子体纳米结构与二氧化钒整合在一起，证明了动态颜色的产生，二氧化钒基于其通过绝缘体-金属过渡的可调光学特性。依靠在局部和传播的表面等离激元的激发以及伍德的异常，在二氧化钒膜上制造出周期性排列的银纳米盘，以实现不同的颜色。通过调整阵列的空间周期性和银纳米盘的直径，可以在整个可见光谱范围内获得各种颜色。进一步，使用二氧化钒的绝缘体-金属过渡，可以通过改变温度来积极调整颜色。基于二氧化钒的相变的动态颜色生成方法可以轻松实现多种颜色图案，从而使其具有多功能性，灵活性和高效率的独特优势，有利于显示和成像技术。
