METHOD OF GRAPHENE QDS FORMATION FOR THE NEXT GENERATION DISPLAY BY USING BLOCK COPOLYMER SELF-ASSEMBLED STRUCTURE

摘要

PURPOSE: A manufacturing method of graphene quantum dots is provided to manufacture graphene quantum dots of a constant size by applying a block copolymer self-assembling process, thereby capable of improving an existing broad PL spectrum performance. CONSTITUTION: A manufacturing method of graphene quantum dots comprises: a step(S1) of spreading a block copolymer on a material layer consisting of a mono-layered graphene; a step(S2) of forming a self-assembled structure of a several to dozens nano meters on the material layer by heat-treating the block copolymer and phase separation; and a step(S3) of etching the material layer by using the self-assembled structure as a mask.
