| Outline of Final Research Achievements |
By combining conventional colloidal template self-assembly technique with monolithic column technique, we established a simple and facile method for the preparation of a monolithic thin film with submicron structure and successfully produced photochromic materials, which exhibited structural color when irradiated with white light. The mechanism of the color emission was studied by examining the light transmission/reflection characteristics in detail. As a result, we concluded that the observed structural color was due to two-dimensional visible light diffraction generated by the periodic submicron structure.
