Disclosed herein is a thin film prepared using a mixture of nanocrystal particles and a molecular precursor. The nanocrystal is used in the thin film as a nucleus for crystal growth to minimize grain boundaries of the thin film and the molecular precursor is used to form the same crystal structure as the nanocrystal particles, thereby improving the crystallinity of the thin film. The thin film can be used effectively in a variety of electronic devices, including thin film transistors, electroluminescence devices, memory devices, and solar cells. Further disclosed is a method for preparing the thin film.

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.
