Abstract:
PURPOSE: A quantum dot light emitting device and a manufacturing method thereof are provided to reduce manufacturing costs by forming a quantum light emitting layer and a charge transport layer by a solution process. CONSTITUTION: An anode(210) is formed in the top of a substrate. A quantum light-emitting layer(230) is formed on the anode and a charge transport particle and a quantum dot are mixed. A cathode is formed on the quantum light-emitting layer. A charge transport particle is an oxide nano particle. The diameter of a quantum dot is 2nm to 20nm. An electron-transport layer(240a) is composed an N-type semiconductor nano particle and is formed on the quantum light-emitting layer.
Abstract:
Disclosed are a quantum dot-block copolymer hybrid, methods of fabricating and dispersing the same, a light emitting device including the same, and a fabrication method thereof. The quantum dot-block copolymer hybrid includes; a quantum dot, and a block copolymer surrounding the quantum dot, wherein the block copolymer has a functional group comprising sulfur (S) and forms a chemical bond with the quantum dot.
