Description

<p>Structural color has attracted considerable research and industrial attentions because the color never diminishes as long as the structure is preserved. However, structural coloration usually utilizes light interference in a periodic structure of sub-wavelength components, and thus the color depends on the viewing angle. In this work, by exploiting Mie resonances of high-refractive index dielectrics, we develop structural color inks composed of crystalline silicon nanoparticles usable for coloration of an arbitrary substrate. Thanks to the high sphericity, high crystallinity, high size purity, and perfect dispersion in a solution, silicon nanoparticle inks exhibit vivid color recognizable by the naked eyes in a range of blue to orange.</p>
