Abstract
The invention discloses a white-light light emitting diode. The white-light light emitting diode is characterized by comprising an n-type gallium nitride film, an antimony doped p-type zinc oxide nanowire array and a positive electrode which are sequentially stacked from the bottom up, wherein the n-type gallium nitride film is contacted with the antimony doped p-type zinc oxide nanowire array to form a heterojunction so as to act as a white-light light emitting layer, the positive electrode is contacted with the antimony doped p-type zinc oxide nanowire array so as to act as a working positive electrode, the n-type gallium nitride film is provided with a negative electrode thereon, and the negative electrode is contacted with the n-type gallium nitride film so as to act as a working negative electrode. The invention further discloses a preparation method of the white-light light emitting diode. Compared with a traditional white-light light emitting diode device, the white-light light emitting diode is simple in process, provided with low color temperature, free of ultraviolet rays, high in safety and suitable for life lighting, and plays an important role in pushing household lighting applications of the white-light light emitting diode in China.
