Abstract

The development of a SERS active substrate using TiO₂ nanotubes with Ag was implemented. TiO₂ NT was produced on glass substrates via RF sputtering of Ti, anodization, and annealing. The TiO₂ and Ag/TiO₂ substrates displayed excellent transparency in the visible light region. The optimum condition for the SERS substrate was concluded to be at 30 minutes photochemical deposition of Ag. The substrates were also exposed to dye solutions followed by characterization for SERS analysis. The Raman signal amplification in the region 210-1300 cm^-1 obtained using the Ag/TiO₂ substrates validates its SERS activity, however the amplification of the dye signals were inconclusive.
