“…Recent advances in nanofabrication and characterisation have contributed to a plethora of investigations into methods of structural coloration, one of the simplest and most scalable being thin film, or Fabry‐Peŕot, coloration, which produces selective reflection based on interference between parallel surfaces in a nanoscale cavity . Anodised aluminium oxide (AAO) is a popular platform for thin film coloration, since a simple electrochemical process creates a dielectric cavity on the surface of the aluminium substrate with a thickness of the order of visible light wavelengths .…”

Existing structural coloration methods using thin films, commonly implemented in high-purity aluminium, produce colours which are highly dependent on the viewing angle because of the inherent angular dependence of thin film interference. Adapting the thin film coloration mechanism to anodisation of industrial-quality aluminium alloys, which scatter light more efficiently than their high-purity counterparts, reduces angle dependence in the colour produced. This reduction of angle dependence, as well as the wide use of anodised aluminium in consumer products, suggests that structural colour based on anodised aluminium could potentially be scaled up for commercial scale production.

lasting durability, and dynamic functionality, which holds great potential in revolutionizing traditional coloring technologies and enabling future-oriented applications such as color printing, digital microdisplay, steganographic cryptography, and, etc. Earlier inspiration from nature such as butterfly wing and flora [1,2] provided a new perspective to utilize photonic bandgap crystal to preferentially diffract light, forming bright structural colors. However, the structural colors by photonic crystal suffers from low resolution [2,3] restricted in principle by large pixel due to wavelength-comparable periodicity and multiple unit cells for exciting coherent Bragg diffraction to form the bandgap. [4] The low resolution in photonic crystal has recently been conquered by emerging plasmonic color printing beyond the diffraction limit, where nanoscale metallic structures can be individually controlled to render diverse colors. [3,[5][6][7][8][9][10][11] By absorbing light at the plasmon resonance frequency, the plasmonic structure will redistribute scattering spectrum which differ from that of input beam, thus rendering plasmonic colors. However, inevitable large absorption of resonant plasmonic system will lead to small scattering cross-sections, so it causes fundamental problems like limited range, degraded color pureness, and low brightness. The low quality of plasmonic color printing also impinges on dynamic functionality which many researches are dealing with recently. The previous methods toward dynamic plasmonic colors include complicate external stimulus like redox hydrogenation/ dehydrogenation, [12,13] mechanical deformation, [14,15] liquidcrystal-combined system, [16,17] and other methods. [18][19][20][21] As other approaches, perovskite nanostructures for in situ dynamic colors and three-dimensional chiral plasmonic gold nanoparticle for polarization-resolved colors have been reported. [22,23] However, most of the dynamic approaches hinders accurate manipulation of color and the miniaturization of the optical devices because of the complicated mechanism.The recent advancement in all-dielectric subwavelength metasurfaces has been applied to many exciting applications such as meta-holograms, [24][25][26][27][28][29] sub-diffraction imaging (metalenses) [30,31] to microprinting. [3,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][32][33][34][35][36][37][38] Due to its capability of controlling the optical properties such as phase and amplitude, [39][40][41][42][43] all-dielectric metasurfaces could be used to circumvent the metallic loss and provide an alternative way for color rendering. Essential fundamental physics is that each subwavelength unit High-quality and tunable structural color printing with feasible fabrication is a key goal in recent decades, holding the possibility for full-color microdisplay and impeccable cryptographic nanoprints. Plasmonic approach suffers from the inevitable material absorption restricting the color spectrum with suppressed lightness. Recent progress in di...

Plasmonic colors are structural colors generated by the resonant interaction of light with metallic nanostructures through surface plasmons. [13] In recent years, plasmonic colors have drawn considerable attention due to their super-high printing resolution, tunable color properties, excellent chemical stability, scalable manufacturability, and environment-friendly recyclability. [13] The potentials of applying plasmonic colors in active displays have been increasingly recognized and various novel device configurations implementing plasmonic colors have been demonstrated, such as metal-nanostructures-array-based color filters for imaging devices, [14][15][16] metal-insulator-metal resonators tuned by modulating refractive index, [17,18] plasmonic color substrates controlled by liquid crystals, [19][20][21] electrochromically switchable plasmonic color devices, [22][23][24] plasmonic colors operated via reversible electrodeposition, [25,26] and aluminum nano-antenna arrays for high-chromaticity color filters in displays. [20] Recently, integrating EC polymers onto plasmonic color substrates has emerged as a very promising direction for developing ECD-based full-color flexible electronic papers. [22,24,27] From technological points of view, such device configurations offer several distinctive advantages. First, the colors are generated from the plasmonic color substrates rather than from the EC polymers, which straightforwardly breakthroughs the limited available colors of the latter. Second, through surface plasmons, plasmonic color substrates can establish strong nanoscale confinement of optical fields and thus require ultra-thin EC poly mer layer (<100 nm thick) for attaining high-contrast control of colors. The flux of material (dopant) to and from the EC polymer film during the doping/dedoping processes, upon the application of a voltage, can be significantly boosted in the ultra-thin film, which can enable unprecedented fast switching speed to display videos. [22,24] Third, plasmonic color substrates can potentially be manufactured on flexible substrates, which opens up an avenue to new applications such as next-generation wearable display devices. Promising up-scalable manufacturing techniques of plasmonic colors or structural colors include roll-to-roll (R2R) nanoimprint, [28] laser-induced photothermal reshaping, [29,30] and inkjet printing. [31,32] Out of these techniques, high-speed R2R nanoimprint has the best overall throughput and allows largearea generic plasmonic color patterns to be replicated onto flexible thin foils. [28] It is noteworthy that plasmonic color pixels manufacturable through R2R process must have surface-relief nanostructures, which are defined on a master stamp surface during its origination procedure.Combining electrochromic (EC) polymers with plasmonic colors is a very promising configuration for realizing full-color, low-power, flexible, reflective displays. From materials perspectives, the polymer material growth and its electrochemical properties, and the plasmonic color subst...
