NANOCRYSTAL MIXTURE AND LIGHT-EMITTING DIODE USING THE SAME

摘要

A nano-crystalline mixture and a light emitting diode using the same are provided to improve the optic use efficiency by minimizing the fluorescence reduction caused by the absorption-resorption in case using the different kinds of semiconductor nano crystal. A blue-LED chip(20) is comprised of a p-type semiconductor and a n-type semiconductor arranged on a packaging frame(10). The luminous layer is comprised of the transparent matrix including the luminous body which covers the blue-LED chip. The transparency resin matrix of the luminous layer altogether includes a green luminescence nano-crystalline composite(40) and a red light emitting nano-crystalline composite(50). The p-type semiconductor of the blue-LED chip is connected to the electrode through a wire(30). The n-type semiconductor is connected to the electrode through the wire.
