Research Abstract

In biological systems, there are so many iridescent colors which are based on the periodic nano-scaled structures. We clarified these structures, and then created artificially the similar structures, exploiting the self-assembly of polymers in conventional fields such as liquid crystal, phase separation, colloidal crystal and so on. Optical properties of these fine materials have been also analyzed for the application to optical devices.
