Abstract This tutorial min review discusses the important features of nanotechnology colour generation by quantum dots (QDs), nanostructured photonic crystals (PCs) and plasmonic metal nanoparticles. Quantum (QDs) are characterized tunable size dependent strong fluorescence emission properties. Photonic generate material independent structural ( iridescent on angle observation ) due to constructive interference arising from Bragg diffraction producing gratings. It causes vibrant in opals pearls, wings peacocks butterflies, necks pigeons, variable colours chameleons, etc. Plasmonic nanoparticles like Au-, Ag- Cu-nanoparticles show both light absorption scattering properties that can be tuned varying size, morphology composition Structural PCs is used nature while colouring QDs man made activities. The based superior organic pigment terms brightness photostability this field an emerging area research with a great promise applications various fields.

Colloidal glasses display angle-independent structural color that is tunable by the size and local arrangement of sub-micrometer particles. While films, droplets, microcapsules with isotropic have been demonstrated, shaping colloidal in three dimensions remains an open manufacturing challenge. Here, a light-based printing platform for into 3D objects featuring complex geometries vivid after thermal treatment reported. Rheology, photopolymerization, calcination experiments are performed to design photoreactive resins leading printable glasses. With help microscopy, scattering, optical characterization, it shown photonic properties printed reflect locally ordered microstructure glass. The capability creating illustrated lattices miniaturized sculpture replicas unique shapes multimaterial designs.

Abstract Thin film‐based structural coloration predominantly uses an elastomeric substrate and active materials, which exhibit uniform color changes under external stimuli such as bending, heat, chemical environments. However, generating distinctive colors in a single stimulation is challenging, especially for microscale pixel arrays, interact more spectral ways than bare thin films or static pixels. This study presents two‐step photo‐cross‐linking fabrication approach monolithic arrays. The pixelated structure devised using ultraviolet‐curable chitosan (UVCC) on polydimethylsiloxane with controlled thickness at the nanoscales. device can generate bending‐based reversible wrinkles different sizes according to of UVCC. Subsequently, each exhibits thickness‐specific covering entire visible spectrum when bent. By coupling four pixels colors, it demonstrated that unit be seen combined eyes. To demonstrate micropixel approach, traditional Korean Dancheong pattern adopted categorized its into three ones. proposed method generates distinguishable between pixels, makes this strong contender pixel‐based applications anti‐counterfeiting, camouflage, security printing.

Abstract With the rapid development and wide application of visible (VIS) infrared (IR) detections, it is necessary to explore visible-infrared (VIS-IR) compatible camouflage. Here, we report a VIS-IR independent camouflage device which composed upper IR-transparent VIS-color-patterned layer lower electrochromic IR layer. The has amorphous photonic structure polystyrene nanospheres (PSNSs). By customizing PSNS size, various colors can be realized for VIS takes advantage multiwall carbon nanotubes (MWCNTs) as electrode well active material. Experimental results reveal that different (including blue, green, purple) have been obtained, emissivity electrically regulated from 0.43 0.9. Moreover, prototype also exhibits good electrical stability hydrophobic characteristic (the water contact angle outmost surface exceeds 120°). These output performances demonstrate success our design strategy promoting finding applied in fields energy conservation fields.
