“…Due to the ability to confine light into sub-wavelength dimensions, LSPR is a natural approach to generate color elements, as illustrated in Figure 2a. 7,[58][59][60][61][62][63][64][65][66][67][68][69][70][71][72] Here, the collective oscillation of free 7 electrons in metallic nanostructures is strongly coupled to external electromagnetic waves forming quasiparticles called plasmons, 73,74 leading to absorption and scattering of light at resonances that are typically several hundreds of nanometers in the wavelength range. The resonance frequency and the resulting color can be controlled by tuning the particle's shape, size, and its surrounding nano environment.…”

Structural colors traditionally refer to colors arising from the interaction of light with structures with periodicities on the order of the wavelength. Recently, the definition has been broadened to include colors arising from individual resonators that can be subwavelength in dimension, e.g., plasmonic and dielectric nanoantennas. For instance, diverse metallic and dielectric nanostructure designs have been utilized to generate structural colors based on various physical phenomena, such as localized surface plasmon resonances (LSPRs), Mie resonances, thin-film Fabry-Pérot interference, and Rayleigh-Wood diffraction anomalies from 2D periodic lattices and photonic crystals. Here, we provide our perspective of the key application areas where structural colors really shine, and other areas where more work is needed. We review major classes of materials and structures employed to generate structural coloration and highlight the main physical resonances involved.

“…The scanning time also reduced by four orders of magnitude than that of recently reported hydrogenation and dehydrogenation-based plasmonic color scanning for the same sample length. [31] Compared to plasmonic colors via laser direct writing, [44][45][46] the plasmonic colors in our scheme were spatially and temporally controlled by using a scanning laser to induce a bubble in the liquid. Our research could open up new possibilities for the generation of ultracompact, efficient, and multi-dimensional multiplexing optical devices.…”

Because of the subwavelength pixel resolution, long‐term stability, and radiation resistance, plasmonic colors show great potential applications in high‐resolution color display, high‐density information storage, and stable color printing. Herein, laser‐induced bubbles are used to realize time‐ and direction‐controllable plasmonic color scanning in a metallic nanohole array, which can give rise to plasmonic colors. When the environment is changed from air to water, the peak wavelength of the metallic nanohole array is redshifted by ≈146 nm, and the color of the metallic nanohole array is changed from purple to yellow. Experimentally, these color changes are demonstrated when the water gradually covers the metallic nanohole array. More importantly, by using laser‐induced bubbles, time‐ and direction‐controllable plasmonic color scanning is achieved by controlling the movement speeds and positions of a control laser. Compared to the current state‐of‐the‐art plasmonic color scanning technology, the scanning time by using laser‐induced bubbles decreases by four orders of magnitude for the same scanning length. The time‐ and direction‐controllable color scanning provides additional degrees of freedom (scanning time and scanning direction), and it may have potential applications in information display, security, storage, and encoding.

“…Plasmonic nanoheating induced by the confined thermal effect has been applied to nanolithography, [43][44][45][46] nanojetting, 47 nanoparticle deformation, [48][49][50] nanophase transitions 51,52 and nanoprinting. 53,54 Here, instead of using global annealing, we locally anneal the TiO 2 films with the assistance of surface plasmons, which generates much smaller domains of phase change compared to UV laser annealing.…”
