摘要： A method for preparing a multilayer of nanocrystals. The method includes the steps of (i) coating nanocrystals surface-coordinated by a photosensitive compound, or a mixed solution of a photosensitive compound and nanocrystals surface-coordinated by a material miscible with the photosensitive compound, on a substrate, drying the coated substrate, and exposing the dried substrate to UV light to form a first monolayer of nanocrystals, and (ii) repeating the procedure of step (i) to form one or more monolayers of nanocrystals on the first monolayer of nanocrystals. Further, an organic-inorganic hybrid electroluminescence device using a multilayer of nanocrystals prepared by the method as a luminescent layer. The luminescent efficiency and luminescence intensity of the electroluminescence device can be enhanced, and the electrical properties of the electroluminescence device can be controlled by the use of the multilayer of nanocrystals as a luminescent layer.

摘要： Example embodiments provide a three-dimensional microfabrication method using photosensitive nanocrystals is provided. The method comprises the steps of preparing a photosensitive composition comprising a photocurable compound and nanocrystals whose surface is coordinated with a compound having a photosensitive group, applying the photosensitive composition to a substrate and drying the photosensitive composition to form a thin film, and subjecting the thin film to three-dimensional microfabrication. According to the method, nanocrystals are arranged in a three-dimensional array to form photonic crystals or a three-dimensional structure. The three-dimensional structure can be used for the fabrication of micro-electro-mechanical systems (MEMS), thus contributing to the manufacture of display devices and electronic devices on a nanometer scale. Example embodiments also provide a display device using the three-dimensional structure of nanocrystals.
