We also tried measurements to demonstrate that hot spots make significant contributions to surface enhanced Raman scattering [34]. For this purpose, the sample of nanoparticie assembly was doped with Raman active molecules by a spincoating method, and near-field excited Raman scattering from the sample was recorded. We adopted Rhodamine 6G dye as a Raman active material, which is...

Figure Cl.5.7. Surface-enhanced Raman speetra of a single rhodamine 6G particle on silver recorded at 1 s intervals. Over 300 speetra were recorded from this particle before the signals disappeared. The nine spectra displayed here were ehosen to highlight several as yet unexplained sudden changes in both frequency and intensity. Reprinted with permission from Nie and Emory [53].

Emory and Nie described a particularly interesting approach the combination of near-field effects from tapered single-mode fiber probes with surface enhanced Raman scattering from single Ag colloidal nanoparticles [113]. By using the combined enhancement effects of molecular (rhodamine 6g) and particle...

To demonstrate the existence of the SPR effect, which was shown to redshift with an increase in NP size, surface-enhanced Raman scattering (SERS) measurements using rhodamine-6G were performed. The study emphasized the efficiency of the resulting antireflection coating, which was fabricated for solar cell applications and was made of black silicon, a silicon nitride passivated layer together with a coating of Ag NPs.

Grochala, Kudelski, and Bukowska [228] have described the anion-induced charge-transfer enhancement in S E RS and S E RRS spectra of rhodamine 6G on Ag electrode as a function of the electrode potential, upon addition of chloride and citrate anions. In a very recent paper, Brolo et al. [229] have discussed the ratio of the surface-enhanced anti-Stokes scattering to the surface-enhanced Stokes-Raman... 

Yan et al. [71] have used a hollow photonic crystal fiber bundle to immobilize multifaceted AuNPs of 100-200 nm diameters within the hollow stmcture (Fig. 12). They launched the excitation light at 633 nm for Raman spectroscopy onto the end fire of the photonic crystal fiber with a x50 objective. The same objective lens was used to collect the scattered light for Raman spectroscopy. The sensing material or analyte was rhodamine B immobihzed and dried within the photonic fiber onto the AuNPs. The Raman spectrum showed a clear surface enhancement in the presence of the AuNPs. Nevertheless the authors used a photonic crystal fiber, no band gap... 

The first approach toward SMD using surface-enhanced resonance Raman scattering was published by Kneipp et al. in 1995 [58]. It involves the use of extremely low dye concentrations (down to 10 M of rhodamine 6 g) adsorbed at silver colloids which were activated by NaCl. The authors estimated that less than 100 dye molecules were enough for recording an SERS spectrum with sufficient signal-to-noise ratio.
