“…Structural color can be produced by various methods, including additive manufacturing [9] [10] , lithography [11] , laser direct writing [12] and colloidal assembly [13] , etc.. Among of them, the two dimensional (2D) photonic crystals (PCs) fabricated by self-assembly strategies such as magnetic assembly, microfluidics, spray coating, and printing, etc., have attracted much attention on account of the simple preparing procedure, low cost and high production efficiency.…”

The structural coloration of two-dimensional photonic crystals has always been a hot topic in recent research. However, how to control the arrangement of nano particles in two-dimensional periodic structure so as to produce specific hue of structural colors with stable physical properties, have become key research content. In order to overcome this drawback, a method of utilizing plasma etching treatment to create structural color modulation on two-dimensional colloidal crystal surfaces by changing the etching power has been proposed. Colors as orange red, yellow, green and blue are obtained with different plasma etching power on planar hexagonal packed structure. The effects of plasma etching power and sizes of PS particles on the optical properties are studied. As a result, the color of samples distributed counterclockwise around white point with increasing the plasma etching power on the a* -b* plane, and changed from orange to blue. Moreover, the diffraction spectrum is also experimentally investigated, and exceed the sRGB gamut boundary. This research can be used in the applications of green printing, anti-counterfeiting and other related fields with low cost.

[39][40][41] For example, the recent electrochromic supercapacitors based on Fabry-Pérot cavity could display a wide variety of fantastic patterns consisting of different, vivid colors, achieving acceptable visual aesthetics.

Multifunction‐integrated semitransparent organic photovoltaic cells (STOPVs), with high power generation, colorful transmittance/reflectance, excellent ultraviolet (UV) protection, and thermal insulation, are fully in line with the concept of architectural aesthetics and photoprotection characteristics for building‐integrated photovoltaic‐window. For the indelible rainbow color photovoltaic window, one crucial issue is to realize the integration of these photons‐ and photoelectric‐related multifunction. Herein, dynamic transmissive and reflective structural color controllable filters, with asymmetrical metal‐insulator‐metal (MIM) configurations (20 nm‐Ag‐HATCN‐30 nm‐Ag) through machine learning, are deliberately designed for colorful STOPV devices. This endows the resultant integrated devices with ≈5% enhanced power conversion efficiency (PCE) than the bare‐STOPVs, gifted UV (300–400 nm) blocking rates as high as 93.5, 94.1, 90.2, and 94.5%, as well as a superior infrared radiation (IR) (700‐1400 nm) rejection approaching 100% for transparent purple‐, blue‐, green‐ and red‐STOPV cells, respectively. Most importantly, benefiting from the photonic recycling effect beyond microcavity resonance wavelength, a reported quantum utilization efficiency (QUE) as high as 80%, is first presented for the transparent‐green‐STOPVs with an ultra‐narrow bandgap of 1.2 eV. These asymmetrical Febry‐Pérot transmissive and reflective structural color filters can also be extended to silicon‐ and perovskite‐based optoelectric devices and make it possible to integrate additional target optical functions for multi‐purpose optoelectric devices.

“…Optical multilayer thin-film structures are common in many device applications, including solar cells, , OLEDs, filters, radiative cooling, etc. Thin-film stacks have been extensively used to produce long-lasting structural colors, − for example, the Toyota structural blue, in contrast to traditional colors and coatings that are made from organic dyes or colored pigments. One such coating is decorative chrome plating (DCP), a metal finishing process widely used in the industry for coating various automobile parts, kitchen appliances, plumbing fixtures, etc.…”

Decorative chrome plating (DCP) continues to be ubiquitous in creating highly appealing metal finishings and coatings, beating out other organic dye-based finishes. However, the hazardous chrome plating process is fraught with adverse health effects for the workers involved and causes significant environmental damage. In this work, we present a multilayer thin film structure to mimic the chrome appearance. To find a design efficiently, we employ a reinforcement learning (RL) algorithm to perform an automatic inverse design. This results in structures composed of environmentally friendly materials that not only have the chrome color but can also achieve additional functions beyond decoration. As an example, one structure is designed to have high transmission in the radio frequency regime, a property that general metals cannot have, which can broaden the decorative chrome applications to include microwave operating devices. The experimental structures are fabricated by physical vapor deposition to demonstrate the indistinguishable chrome color and validate the effectiveness of the RL inverse design approach.
