Figure 6

Raman spectra of methylene blue (MB) molecules on porous gold and glass substrate (a) and Au/Ag alloys (b). For (a) the measurements have been performed on glass (blue curve), untreated (black), high fluency region (green), Low fluency region (red). For (b) the measurements have been performed on untreated (black), high fluency region (green), Low fluency region (red).
