摘要： Disclosed herein is a method for preparing a multilayer of nanocrystals. The method comprises 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.

摘要： A method of fabricating a semiconductor structure comprises forming a quantum dot. An insulator layer of silica is then formed encapsulating the quantum dot to create a coated quantum dot, using a reverse micelle sol-gel reaction. In one embodiment, the reverse micelle sol-gel reaction includes dissolving the quantum dot in a first non-polar solvent to form a first solution, adding the first solution to a second solution having a surfactant dissolved in a second non-polar solvent; and adding sodium silicate, potassium silicate, or lithium silicate to the second solution.

摘要： The present invention relates to a coating composition having excellent wavelength conversion efficiency and a wavelength converting thin film/sheet prepared using the same. The coating composition of the present disclosure includes 1 to 60 wt % of polyorgano-silsesquioxane, 0.0001 to 30.0 wt % of a wavelength converting agent, and a solvent, and exhibits a transmittance of 70% or more as compared to that of an aqueous solution. A wavelength converting thin film/sheet prepared by using the coating composition has not only excellent photoluminescence, thermal resistance, and light-fastness, but also moisture and oxygen permeability is low, and the visible light transmittance thereof is 70% or more as compared to that of the air, and when patterning is added, the photoluminescence intensity of sheet is at least two-fold higher than that of a non-patterned sheet. Therefore, the coating composition of the present invention may be conveniently used in the preparation of a wavelength converting thin film/sheet, and feasibly applied to the preparation of a solar cell in an efficient manner.
