Multiphoton Photo-Emission (MPPE) based on Localized Surface Plasmon Resonances by ZnO Nanorods Array with Au Particles

Abstract

Here, we propose the optical-assisted emission mechanism based on Localized Surface Plasmon Resonances (LSPRs) enhancement effect to improve the electron emission performance of ZnO nanorod arrays (ZNAs). By preparing gold nanoparticles on the surface of ZNAs, we proved that the low strength of the driving electric field is outstanding performance in the application of Multiphoton photo-emission and the effects of optical assistance on field emission performance of modified Au-ZNAs were investigated.
