NANOCOMPOSITE HAVING QUANTUM DOTS FOR WAVELENGTH SHIFTER AND A PREPARATION METHOD THEREOF

摘要

PURPOSE: A nano-composite including quantum dot for wavelength conversion and a manufacturing method thereof are provided to improve light stability and luminous effect and to have irreversible property by performing annealing processing at high temperature. CONSTITUTION: A manufacturing method of nano-composite comprises the following steps: obtaining a mixture by mixing quantum dot and polymer; obtaining annealing-processed mixture by performing annealing process; and obtaining nano-composite including the quantum dot by irradiating UV on the annealing processed mixture. The annealing is performed at 100-170 deg. Celsius for 1-3 hours. The UV irradiation is processed with UV intensity of 30-50W, wavelength of 20-40 nano meters and exposure time of 1-24 hours.
