Fano Resonant Optical coatings platform for Full Gamut and High Purity Structural Colors

Year: 2022

Type: preprint

Abstract: 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 display technologies, colorful solar panels, steganography, décor, data storage, and anticounterfeiting measures. We show that optical coatings exhibiting the photonic Fano Resonance present an ideal platform for structural coloring- they provide full color access, high color purity, high brightness, controlled iridescence, and scalable manufacturing. 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 have a significant advantage over existing structural coloring schemes.
