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.
