Artificial Structural Color Pixels: A Review

Abstract

Inspired by natural photonic structures (Morpho butterfly, for instance), researchers have demonstrated varying artificial color display devices using different designs. Photonic-crystal/plasmonic color filters have drawn increasing attention most recently. In this review article, we show the developing trend of artificial structural color pixels from photonic crystals to plasmonic nanostructures. Such devices normally utilize the distinctive optical features of photonic/plasmon resonance, resulting in high compatibility with current display and imaging technologies. Moreover, dynamical color filtering devices are highly desirable because tunable optical components are critical for developing new optical platforms which can be integrated or combined with other existing imaging and display techniques. Thus, extensive promising potential applications have been triggered and enabled including more abundant functionalities in integrated optics and nanophotonics.

Strong Interference in Planar, Multilayer Perfect Absorbers: Achieving High-Operational Performances in Visible and Near-Infrared Regimes

“…In recent work, we theoretically demonstrated that noble metals can offer strong absorption in ultraviolet and visible (Vis) parts of the EM spectrum, while lossy metals can extend the upper-absorption edge up to the near-infrared (NIR) region [1]. Experimentally, these findings have been demonstrated in many recent research studies [17]- [44]. In one pioneering study, Mattiucci et al showed that impedance matched with thin metamaterials make metals absorbent [26].…”

Self‐Assembly of Colloidal Particles for Fabrication of Structural Color Materials toward Advanced Intelligent Systems

“…In addition, a huge demand for advanced display technology is placed with the rapid development of mobile and electronic devices and becoming increasingly important in our daily life. Owing to the low power consumption as well as full‐color emission, structural color materials are highly hopeful for constructing optical display devices . In particular, the production of a tunable pattern with well‐arranged primary colors of red, green, and blue (RGB) units is anticipated, which can be achieved via colloidal assembly along with other techniques like micromolding, printing, or lithography.…”

Metal-Based Graphical SiO2/Ag/ZnS/Ag Hetero-Structure for Visible-Infrared Compatible Camouflage

“…With the rapid development of modern detection industries, traditional single stealth approaches, such as visible-light camouflage [ 1 , 2 ] and infrared emissivity engineering [ 3 , 4 , 5 , 6 ], are severely threatened by dual- and multi-approach target detectors [ 7 , 8 ], which were proposed and practically applied in recent years. Hence, the impending compatible camouflage demand of visible light and infrared has aroused extensive research interests, such as developing colored photonic crystals [ 9 ] and chemical pigments [ 10 , 11 ]. Nevertheless, complicated technology and non-controllable colors are still direct obstacles for the large-scale application of camouflage combined with various structure colors and ultra-low emissivity ( ε ).…”
