Abstract: An optoelectronic diode may include a first electrode, a second electrode, a third electrode, a first active layer between the first and second electrodes, and a second active layer between the second and third electrodes. Two of the electrodes may be electrically connected to each other and may have different resistances. The first and second active layers may be isolated from each other. The first active layer, the first electrode, and the second electrode may form a diode, and the second active layer, the second electrode, and the third electrode may form a diode. The second electrode may have a refractive index different from a refractive index of the second active layer.

Abstract: Disclosed herein is a quantum dot phosphor for light emitting diodes, which includes quantum dots and a solid substrate on which the quantum dots are supported. Also, a method of preparing the quantum dot phosphor is provided. Since the quantum dot phosphor of the current invention is composed of the quantum dots supported on the solid substrate, the quantum dots do not aggregate when dispensing a paste obtained by mixing the quantum dots with a paste resin for use in packaging of a light emitting diode. Thereby, a light emitting diode able to maintain excellent light emitting efficiency can be manufactured.
