Figure 7From: Nanostructured Silver Substrates With Stable and Universal SERS Properties: Application to Organic Molecules and Semiconductor NanoparticlesNormalized Raman spectra of the same NPs sample with plasmon enhancement (grey) and without it (black). The SERS spectrum is same as in Fig. 6 for Tann = 430°C. The ordinary spectrum was obtained by deposition of NPs from a highly concentrated solution onto the bare Si surfaceBack to article page
