Structural coloration generates colors by the interaction between incident light and micro- or nano-scale structures. It has received tremendous interest for decades, due to advantages including robustness against bleaching environmentally friendly properties (compared with conventional pigments dyes). As a versatile strategy, tuning of structural based on nanoscale photonic structures been extensively explored can enable broad range applications displays, anti-counterfeiting, coating. However, scholarly research had limited impact commercial products because their disadvantages in cost, scalability, fabrication. In this review, we analyze key challenges opportunities development colors. We first summarize fundamental mechanisms design strategies while reviewing recent progress realizing dynamic coloration. The promising potential optical information processing displays are also discussed elucidating most prominent that prevent them from translating into technologies market. Finally, address new underexplored community but be achieved through multidisciplinary within emerging areas.

Abstract Feynman's statement, “There is plenty of room at the bottom”, underscores vast potential atomic scale, envisioning microscopic machines. Today, this vision extends into 3D space, where thousands atoms and molecules are volumetrically patterned to create light‐driven technologies.

Structural colors are produced by the diffraction of light from microstructures. The collective arrangement substructures is a simple and cost-effective approach for structural coloration represented colloidal self-assembly.

Microprinting is changing anti-counterfeit technology by producing complex micro-/nano-scale labels to increase the security level. However, current microprinted anti-counterfeiting only contain 2D features, thought of as single coding (e.g. mostly in texts or graphs), unable satisfy high-end demands multi-coding, high-storage-density labels. Here, we introduce an approach for fluorescence printing produce a 3D colourful, sophisticated label. In method, pre-synthetic QDs are printed with photoresists based on two-photon polymerisation, allowing accurate regulation both and 3D.

The multipole interference (MPI) effect plays pivotal roles in the formation of electromagnetic responses various settings. In optics regime, it has been realized typically through Mie resonance that necessitates high‐index, deep‐subwavelength‐scale dielectric resonators are challenging to fabricate. Herein, a new, diffraction‐based MPI scheme can be with low‐index, mesoscale structures is demonstrated. It verified this “diffractive MPI” concept by realizing states using micrometric polymeric cuboids fabricated soft‐lithography. Subsequent analyses reveal distinct near‐zero forward scattering (NZFS) characteristic played crucial shaping cuboid's transmission spectrum. A hitherto unreported NZFS state, which exhibits unique, “trifolium” radiation pattern, also identified. spectral position such turns out strongly dependent on geometry. By combining these results, diffractive related important phenomena induced transparency and structural color generation.

Abstract Structural coloration, a color-generation mechanism often found in nature, arises from light–matter interactions such as diffraction, interference, and scattering, with micro- nanostructured elements. Herein, we systematically study anisotropic, 3D-architected grating structures polarization-tunable optical properties, inspired by the vivid blue of Morpho butterfly wings. Using two-photon lithography, fabricate multilayered gratings, varying parameters height (through scanning speed laser power), periodicity, number layers. In transmission, significant color transitions to brown were identified when structural incident light polarization conditions (azimuthal angle ellipticity). Based on thin film diffraction efficiency theory Raman–Nath regime, characterization results are analytically explained, evaluating impact each parameter variation. Overall, these findings contribute technological implementations polarization-sensitive, gratings for applications.
