    摘要: The present invention relates to a photodetector using nanoparticles, and more particularly, to a novel photodetector wherein surfaces of nanoparticles synthesized by a wet colloidal process are capped with organic materials which then serve as channels for electron migration, or nanoparticles, from which organic materials capped on the surfaces of nanoparticles are removed to form a close-packed particle structure, directly serve to transport electrons. In accordance with specific embodiments of the present invention, it is possible to improve performance of the photodetector and simplify the manufacturing process thereof.

    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, a method for fabricating the nanocrystal electroluminescence device.
