▎ 摘　　要

NOVELTY - A block copolymer is coated on a material layer consisting of a single layer graphene. A self-assembled structure of several tens of nm size is formed on the material layer by heat-treatment and phase-separation. The material layer is then etched by using the self-assembled structure as a mask, to obtain graphene quantum dots. USE - Manufacture of graphene quantum dots for next-generation displays. ADVANTAGE - The method enables manufacture of graphene quantum dots of desired size with broad photoluminescence spectral characteristics. Since the size of quantum dots can be controlled, control of wavelength of light and implementation of red-green-blue color are eased. The obtained quantum dots have excellent brightness and color gamut, and provide highly efficient next-generation displays.
