Abstract
SERS substrate was fabricated by depositing silver on anodized aluminum oxide (AAO) template. The thickness of the AAO template was 200 nm with 40 nm circular pore and 15 nm spacing. SERS effect was observed on these metal coated structures due to electric field enhancement around the edge of the pores. Para-Nitrophenol (pnp) solution of 10−6 M concentration was detected which refers to an enhancement factor of 104.
