    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： A surface emitting device using a photonic crystal includes a two-dimensional slab type photonic crystal structure including a first dielectric layer and a second dielectric layer formed on top of the first dielectric layer wherein a plurality of air holes in a two-dimensional lattice pattern are formed on the surface of the second dielectric layer; a light-emitting material layer formed on the inner wall of the air holes; and optical pumping means for irradiating the lateral surface of the photonic crystal structure with light. The surface emitting device shows improved surface emission efficiency and can advantageously emit light close to monochromatic light. Therefore, the surface emitting device can be used to manufacture a surface emitting laser. A method for fabricating the surface emitting device is also disclosed.

    摘要： A method for preparing cadmium sulfide nanocrystals emitting light at multiple wavelengths. The method comprises the steps of (a) mixing a cadmium precursor and a dispersant in a solvent that weakly coordinates to the cadmium precursor, and heating the mixture to obtain a cadmium precursor solution, (b) dissolving a sulfur precursor in a solvent that weakly coordinates to the sulfur precursor to obtain a sulfur precursor solution, and (c) feeding the sulfur precursor solution to the heated cadmium precursor solution maintained at a high temperature to prepare cadmium sulfide crystals, and growing the cadmium sulfide crystals. Further, cadmium sulfide nanocrystals prepared by the method. The cadmium sulfide nanocrystals have uniform size and shape and can emit light close to white light simultaneously at different wavelengths upon excitation. Due to these characteristics, the cadmium sulfide nanocrystals can be applied to white light-emitting diode devices.
