Raman Rhodamine molecules

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...

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.
