    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.

    摘要: Disclosed is a preparation method of multi-shell nanocrystals in one pot. In an embodiment, a core is formed from a precursors in the presence of solvent and then, without a core separation step, two or more kinds of precursors are added sequentially to dispose a shell on the surface of the core. The method provides a scaleable process suitable for mass production of high quality multi-shell nanocrystals, having diverse bandgaps and high luminescence efficiency. The method does not use a core separation procedure after core synthesis.
