MULTILAYERED WHITE LIGHT EMITTING DIODE USING QUANTUM DOTS AND METHOD OF FABRICATING THE SAME

摘要

A multilayered white light emitting diode and a method of fabricating the same include forming a phosphor mixture layer including a green phosphor and a blue phosphor on a UV light emitting diode and forming a red quantum dot layer on the phosphor mixture layer. In the white light emitting diode of the present invention, the quantum dots are excited by green and blue visible light, thus increasing luminescence efficiency and realizing stable white light. Moreover, the white light emitting diode can be widely used as a light source having high output and high efficiency, thus being capable of substituting for a backlight unit of an illumination device or display device.
