论文摘要
结构着色是一种可光稳定且对环保的着色方法，可利用光学干扰和纳米光子共振，以获取颜色，并具有一系列应用，包括隐肌，装饰，数据存储和抗抗复力措施。我们表明，表现出光子Fano共振的光学涂料是结构着色的理想平台 - 它提供了完整的颜色访问，高色纯度，高亮度，可控的虹彩和可扩展的制造性。我们表明，沉积在FANO谐振光学涂层（Frocs）上的额外的氧化膜增加了颜色纯度（最高97％）和颜色域覆盖范围（SRGB和Adobe颜色空间的覆盖率> 99％）。对于不需要高空间分辨率的着色应用，Frocs比现有的结构着色方案提供了显着优势。
Structural coloring is a photostable and environmentally friendly coloring approach that harnesses optical interference and nanophotonic resonances to obtain colors with a range of applications including steganography, décor, data storage, and anticounterfeiting measures. We show that optical coatings exhibiting the photonic Fano Resonance is an ideal platform for structural coloring -- it provides full color access, high color purity, high brightness, controlled iridescence, and scalable manufacturability. We show that an additional oxide film deposited on Fano resonant optical coatings (FROCs) increases the color purity (up to 97%) and color gamut coverage range (> 99% coverage of the sRGB and Adobe color spaces). For coloring applications that do not require high spatial resolution, FROCs provide a significant advantage over existing structural coloring schemes.
