Field emission from Au nanoparticles decorated ZnO nanowires

ZnO nanowires with Au nanoparticle decoration were prepared. Photoluminescence results reveal quenching of both the band edge and visible emissions of ZnO nanowires after the Au nanoparticle decoration. The field emission properties from Au nanoparticles decorated ZnO nanowires were measured and increasing turn-on fields were observed. The observed phenomena wereattributed to electron transport between ZnO and Au nanoparticle.
