▎ 摘 要
NOVELTY - The device has a cathode formed on a substrate. A hole transporting layer is formed on the cathode. A light emitting layer is formed on the hole transporting layer. An electron transporting layer is formed on the light emitting layer, where the light emitting layer includes a blue graphene quantum dot, a green graphene quantum dot, a red graphene quantum dot and a yellow graphene quantum dot. An anode is formed on the electron transporting layer. Sizes of the graphene quantum dots are less than 100 nm. USE - LED i.e. Zinc oxide-graphene hybrid-type white color LED using graphene quantum dot. ADVANTAGE - The LED has low light emitting efficiency when the LED utilizes a quantum dot including low quantum efficiency so as to easily overcome stability problems in a high-temperature deposition equipment when organic material is applied, thus reducing required costs for manufacturing a device. The hole transporting layer has high flexibility when the hole transporting layer includes material formed by chemical bonding of the graphene quantum dot. DETAILED DESCRIPTION - The blue graphene quantum dot, the green graphene quantum dot and the red graphene quantum dot are made of carbon fiber material. An INDEPENDENT CLAIM is also included for a method for manufacturing a light emitting device using graphene quantum dot. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an LED structure.
