Metal oxide-based silver substrates for surface-enhanced Raman scattering
- Univ. of Memphis, TN (United States)
New substrates were prepared by using sol-gel process for metal oxide (MgO and TiO{sub 2}) undercoating and by using chemical reduction method for silver coating. The substrates were found to exhibit strong Surface-Enhanced Raman Scattering (SERS) signals for benzoic acid (BA), terephthalic acid (TPA), p-nitrobenzoic acid (PNBA), p-aminobenzoic acid (PABA), p-nitrophenol (PNP), and p-nitroanaline. Optimization of metal oxide undercoating and silver deposition was conducted to obtain intense SER band of BA. It was shown that the substrates could be reused for the SER investigation of different samples. A study of the solvent effect on the SERS intensity of BA was conducted; an explanation to the result was suggested.
