Abstract:
The present invention discloses a high-efficiency lighting device and a method for fabricating the same. The method of the present invention comprises steps: providing an insulation substrate and sequentially forming an electrode layer and a seed layer on the insulation layer; forming a plurality of zinc oxide micro and nano structures and a plurality of first insulation units on the seed layer, wherein each zinc oxide micro and nano structure is arranged between two neighboring first insulation units; forming a nitride layer on the side wall of each zinc oxide micro and nano structure; and forming an electrode layer on each nitride layer. The present invention achieves a high-efficiency lighting device via growing nitride layers on the side walls of zinc oxide micro and nano structures. Further, the present invention can reduce the fabrication cost.
