Abstract (EN): This work aims to apply photonic-crystal-based nanocoatings with unusual aesthetical orientation to wood application. Structural colors are currently a formula to achieve those colorful coatings including nonfading properties. They can be produced from self-assembled colloidal spheres into photonic crystals, which possess particular optical properties. Herein, photonic crystals with iridescent structural colors were prepared from the self-assembly of monodispersed nanospheres. Particle sizes can be adjusted from 308 to 196 nm, and well-ordered structures are arranged through self-assembly process into films, which exhibit brilliant colors over a wide visible spectrum, from red to violet. Color varies with the angle of observation of incidence light. The present study provided an effective and simple approach to prepare structural color films and their practical application to wood coating for an aesthetic appeal.
