Ag Nanorod Arrays for SERS: Aspects of Spectral Reproducibility, Surface Contamination, and Spectral Sensitivity
Original language description
Ag nanorod arrays prepared by oblique angle vapor deposition (OAD) represent regular, large area substrates for surface-enhanced Raman scattering (SERS) spectroscopy. We studied uniformity and spectral reproducibility of silver OAD-fabricated substrates(AgOADs) by spectral mapping of methylene blue. The results demonstrate good reproducibility apart from occasional "hot-spot" sites where the intensity is higher. The number of "hot-spots" represents 2%-6% of SERS-active sites of mapping substrate area.We were able to obtain good SERS spectra of testing amino acid tryptophan at 1 x 10(-5) M concentration and three different free-base porphyrins down to similar to 10(-7) M concentration. We found out that keeping the AgOADs in a vacuum chamber overnightprevents the surface from binding any contaminants from the ambient atmosphere, without significant reduction in the SERS enhancement. Such substrates provide stable SERS enhancement even when stored for 1 year after preparation.
