Structural color materials that do not use pigments (developed product)
The bright colors of organisms such as morpho butterflies and tadpoles are colored by a mechanism called structural color. It is a mechanism that produces color due to diffraction and interference of light due to a regular structure at intervals similar to the wavelength of light, rather than by light absorption by light absorption.
We have developed structural color materials that do not use pigments or dyes as new color materials.

Techniques for expressing structural colors
Monodisperse fine particle synthesis technology x periodic array technology
The material that expresses structural color is called photonic crystal and has a nanoperiodic structure whose refractive index changes at intervals similar to the wavelength of light. Photonic crystals exhibit characteristic color and optical properties, such as vivid color development and color changes depending on the viewing angle, due to light diffraction and interference when light is inrushed.
Photonic crystals are classified into several types according to their structure, but since we have a high degree of design freedom, we focused on colloidal crystals with a structure in which fine particles are arranged in a three-dimensional order.
