摘要

基于金属或电介质纳米结构的彩色印刷由于其前所未有的亚波长分辨率而彻底改变了色彩科学。显然，在实际应用中，用智能材料主动控制这种结构颜色的进化正在进行中。在这里，我们通过实验证明了具有高强度和纯度的大色域，以及仅基于三氧化钨（WO3）圆柱形谐振器的开关。由于WO3的电致变色特性，在+2.0 V和- 0.3 V的交变电压下，可以可逆地开启和关闭这些WO3超表面可见光谱范围内的强共振。我们的方法为商业智能窗口的功能多样化以及未来新显示技术的发展开辟了可能性。

Inorganic Electrochromic Metasurface in the Visible

Color printing based on metallic or dielectric nanostructures has revolutionized color science due to its unprecedented subwavelength resolution. Evidently, the evolution toward the active control of such structural colors with smart materials is in progress for real applications. Here we experimentally demonstrate a large color gamut with high intensity and purity, as well as switching on and off based solely on tungsten trioxide (WO₃) cylindrical resonators. The strong resonances in the visible spectral range in these WO₃ metasurfaces can be reversibly switched on and off due to its electrochromism by applying alternating voltages of +2.0 V and −0.3 V. Our approach opens up possibilities for the functional diversification of commercial smart windows, as well as the development of new display technologies in the future.
