摘要： A nanocrystal electroluminescence device comprising a polymer hole transport layer, a nanocrystal light-emitting layer and an organic electron transport layer wherein the nanocrystal light-emitting layer is independently and separately formed between the polymer hole transport layer and the organic electron transport layer. According to the nanocrystal electroluminescence device, since the hole transport layer, the nanocrystal light-emitting layer and the electron transport layer are completely separated from one another, the electroluminescence device provides a pure nanocrystal luminescence spectrum having limited luminescence from other organic layers and substantially no influence by operational conditions, such as voltage. Further included is a method for fabricating the nanocrystal electroluminescence device.

摘要： 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.

摘要： Methods for producing nanoparticle thin films are disclosed. According to one of the methods, a nanoparticle thin film is produced by modifying the surface of nanoparticles to allow the nanoparticles to be charged, controlling an electrostatic attractive force between the charged nanoparticles and a substrate and a repulsive force between the individual nanoparticles by a variation in pH to control the number density of the nanoparticles arranged on the substrate.
