Abstract
As a compromising material for future optoelectronic devices, ZnO attracted many concentrations for its wild applications. Compared with traditional LED fabrication, the technology for the nanoparticle based LED is relatively simple and less cost1, 2. But the emission efficiency needs to be increased. P-type ZnO nano particles were produced by arc-vapor technique and n-type ZnO thin film were produced by MOCVD and sputtering. The light enhancement mechanism of SPP is based on electronic waves coupling between the metal nanostructures and the semiconductor emissions. We use metal particles LSP effect on ZnO nanoparticle based LEDs which is more convenient for varied wavelength light emitting enhancement.
