Abstract

We have elaborated substrates for surface enhanced Raman scattering (SERS) based on carbon nanowalls (CNW) deposited with Ag nanoparticles and thin Ag films. For carbon nanowalls deposited with silver nanoparticles, the achieved analytical enhancement factor SERS was from 50 to 2500. Much higher analytical enhancement factor of SERS, up to 5×10⁴, was obtained for carbon nanowalls deposited with thin Ag film. In this case the SERS signal is determined by fractal structure of carbon nanowalls covered by Ag films. Such fractal structure provides a strong inhomogeneous localization of light, formation of a large number of hot spots and leads as a result to significant enhancement of SERS signal.
