文摘

Novel gold nanospheres top-contact ZnO nanorods arrays were fabricated via combination of self-assemble nanosphere lithography and low-cost hydrothermal chemical method. Gold nanoparticles of different geometries are used to enhance the fluorescent properties of ZnO nanorods based on localized surface plasmonic resonances. The results show that defect-related emission intensity ratio of the ZnO nanorods arrays can be improved up to two orders, and the defect-related emission peak red-shifted from 577 to 623 nm. This improvement is attributed to the enhanced localized surface plasmonic absorption of gold nanoparticles, which implies a promising application in surface plasmonic enhanced spectra.
