Figure 4From: Mildly reduced graphene oxide-Ag nanoparticle hybrid films for surface-enhanced Raman scatteringRaman spectra of Rh123 molecules on different substrates. a) In ethanol solution, b) on MR-GO monolayer, and c) on Ag films and MR-GO-Ag NP hybrid films. The asterisks indicate the Raman peak of Si at 520 cm-1.Back to article page
