초록/요약
Dynamically controllable reflective structural colors have been garnering growing attention due to increasing commercial interests in smart displays (e.g., colorimetric labels), colored e-readers, etc. To comply with the requirements of future displays, several strategies have been proposed by various research groups to achieve wide color tuning ranges in the visible regime, high on/off contrast ratios, and fast response times. In this review, we first introduce ways to create optical resonances including plasmonic, photonic, and plasmonic-photonic hybrid structures that form the basis of color generation. We then outline strategies that control the refractive index contrast between the system and the surrounding as a means to actively change the reflective structural colors, backed with representative examples from the literature. Finally, we provide a comparison of dynamic structural colors based on various switching mechanisms summarizing performance metrics that are important for future displays, and conclude with an outlook on current challenges.
