GRAPHENE QUANTUM DOT LIGHT EMITTING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A graphene quantum dot light emitting and a manufacturing method thereof are provided to form a band gap of a graphene quantum dot layer small by controlling size and shape of a graphene quantum dot. CONSTITUTION: First graphene(20) is n-type graphene. Second graphene(40) is p-type graphene. A graphene quantum dot layer(30) is located on the first graphene. The graphene quantum dot layer comprises a plurality of graphene quantum dots. The graphene quantum dot layer contain organic solvents. The second grapheme is located on the graphene quantum dot layer. An electron transport layer is located between the n-type grapheme and the graphene quantum dot layer. A hole transport layer is located between the graphene quantum dot layer and the p-type graphene.
