Abstract

Metallic substrates with ordered morphology have been shown to be very effective for surface-enhanced Raman scattering (SERS). The sensitivity of detection is increased by several orders of magnitude by using this technique. In this paper we investigate SERS on thermal evaporated gold layer/porous silicon substrate comparatively to the commercial SERS active substrate (Klarite) and we demonstrate the reproducibility of the response.
