A comparison of surface enhanced Raman scattering property between silver electrodes and periodical silver nanowire arrays

---

Abstract.
Surface enhanced Raman scattering (SERS) properties of silver electrodes and periodical silver nanowire
arrays were studied and compared. The silver electrode was fabricated by applying oxidization–
reduction cycle (ORC) voltage on a high purity (99.999%) silver sheet in 0.2 M KCl solution and the
periodical nanowire arrays were fabricated by assembling silver nanowire into the anodic alumina
membrane (AAM) using electrochemical deposition. The AAM was then partly removed to make
nanowire tips emerge for detection. Raman spectra of 106 M, 109 Mand 1012 MRhodamine 6G (R6G)
aqueous solutions were measured separately from each sample with a 514.5 nm air-cooled argon ion
laser source. The results show that periodical nanowire arrays have a more obvious SERS property than
that of the ORC roughened silver electrodes. As-fabricated nanowire arrays have great potential in
organic chemical detection, such as R6G, via measuring SERS spectrum of organic chemicals.
