Abstract
ZnO/Ag composite nanoarrays structure have been successfully prepared through a very simple deposition method. The adherence of Ag nanoparticles to ZnO nanoarrays was realized through the deposition under normal temperature. Due to their exceptional properties, these composite nanoarrays were used as substrate in surface-enhanced Raman scattering (SERS) measurement. SERS signals of typical analytes such as Rhodamine 6G (R6G) were observed from the ZnO/Ag composite nanoarrays, which the results shows that the SERS signals can be detected when the concentration of R6G was 1×10−9 M. This work provides a new method to prepare SERS substrates for SERS detection.
