In addition to colorant-based pigmentation, structure is a major contributor to a material's color. In nature, structural color is often caused by the interaction of light with dielectric structures whose dimensions are on the order of visible-light wavelengths. Different optical interactions including multilayer interference, light scattering, the photonic crystal effect, and combinations thereof give rise to selective transmission or reflection of particular light wavelengths, which leads to the generation of structural color. Recent developments in nanofabrication of plasmonic and carbon nanostructures have opened another efficient way to control light properties at the subwavelength scale, including visible-light wavelength selection, which can produce structural color. In this Concept, the most relevant and representative achievements demonstrated over the last several years are presented and analyzed. These plasmonic and carbon nanostructures are believed to offer great potential for high-resolution color displays and spectral filtering applications.
除了基于着色剂的色素沉着外，结构也是材料颜色的主要贡献者。在自然界中，结构色通常是由光与介电结构相互作用引起的，其尺寸与可见光波长相当。不同的光学相互作用，包括多层干涉、光散射、光子晶体效应以及它们的组合，导致特定波长的光选择性透射或反射，从而产生结构色。近年来，等离子体和碳纳米结构的纳米制造技术的发展为在亚波长尺度上控制光特性开辟了另一种有效途径，包括可见光波长选择，这可以产生结构色。在本综述中，介绍和分析了过去几年中最相关和最具代表性的成就。这些等离子体和碳纳米结构有望为高分辨率彩色显示器和光谱滤波应用提供巨大潜力。
