Manufacturing method of poly-wavelength light-emitting diode of utilizing nano-crystals and the light-emitting device therefor

摘要

A producing method of poly-wavelength light-emitting diode of utilizing nano-crystals and the light-emitting device thereof includes growing and processing a multiple-quantum-well layer based on stacking the mixture of at least two kinds of quantum wells to produce a two-wavelength light-emitting diode. Then, attaching nano-crystals on the two-wavelength light-emitting diode to transfer one of the wavelengths of the two-wavelength light-emitting diode to produce a poly-wavelength light-emitting diode. The device of the present invention can emit blue, green and red lights to produce white light.
