摘要

We have fabricated Ag-decorated ZnO nanoplate arrays by combining water-bath heating toward ZnO hexagonal nanoplate arrays and subsequent decoration of Ag films or nanoparticles on the ZnO surfaces by magnetron sputtering or photoreduction. Experimental surface-enhanced Raman scattering (SERS) results show that Ag-film-ZnO hybrid substrates with different Ag sputtering times exhibit a large difference in enhanced SERS signals for Rhodamine 6G (10~(-7) M). Atomic force microscope analysis reveals that two kinds of positions create abundant "hot spots" in this SERS substrate: one is located at the gap between adjacent separate Ag-film-ZnO hybrid nanoplates, and the other is located at the V-grooves formed by two adjacent interlaced Ag-film-ZnO hybrid nanoplates. The effects of simultaneous changes in interplate spacing and groove wall angle are considered to be the key factors affecting the SERS of our prepared Ag-film-ZnO hybrid substrates, which have also been evaluated by finite-difference time-domain simulation.
