USE - Used as a graphene light-emitting device such as LED or laser diode. ADVANTAGE - The graphene light-emitting device can be economically and rapidly manufactured with excellent photoluminescence efficiency, high flexibility and emission of brightness and improved mechanical characteristics and without white and black spots. DETAILED DESCRIPTION - The graphene light-emitting device (10) comprises a p-type graphene (13) doped with a p-type dopant, an n-type graphene (17) doped with an n-type dopant, and an active graphene (15) that is disposed between the p-type graphene and the n-type graphene and emits light. The p-type graphene, the n-type graphene and the active graphene are horizontally disposed, and are supported by a substrate (11). The active graphene: comprises a graphene superlattice that has a multiple quantum well potential, and graphene quantum dots dispersed between the p-type graphene and the n-type graphene; and is a graphene that is functionalized by attaching a functional group to a surface or edge of the graphene. The graphene superlattice comprises a graphene nanoribbon having a band shape connecting the p-type graphene to the n-type graphene, and periodically arranged quantum dot patterns. One of opposite edges of the graphene nanoribbon has a zigzag shape. A width of each of the graphene nanoribbon periodically changes within 3-20 nm. An interval between adjacent graphene nanoribbons of the graphene nanoribbon is 2-19 nm. The graphene nanoribbon extends parallel to boundaries of the p-type graphene and the n-type graphene between the p-type graphene and the n-type graphene. A first region in which the graphene superlattice is disposed and a second region in which graphene quantum dots are disposed and are alternately arranged partially overlap. The graphene quantum dots comprise three different sizes respectively corresponding to a red photoluminescence, a green photoluminescence, and a blue photoluminescence, and two different shapes. The p-type graphene is horizontally spaced from the n-type graphene. An INDEPENDENT CLAIM is included for a method of manufacturing a graphene light-emitting device.
