Your story matters Citation Zhu, Wenqi. Plasmonics for surface-enhanced Raman scattering: from classical to quantum. Doctoral dissertation, Harvard University. Surface-enhanced Raman scattering (SERS) provides a sensitive method for detecting trace levels of a wide range of chemical and bio-chemical compounds adsorbed on nanostructured plasmonic metal surfaces 1,2, most commonly used metals include silver, gold and copper process is related to normal Raman scattering, where a small fraction of incident laser Cited by:
Raman scattering spectra of 4H-SiC with different carrier concentrations were measured from 90 K to K. By using the improved empirical formula and the energy-time uncertainty relation, temperature and doping dependence of Raman shift and phonon lifetimes were studied. For the folded transverse acoustic (FTA) and longitudinal optical (FLO) mode with E2 symmetry, the Cited by: 2. History of Raman Scattering. – Inelastic light scattering predicted by A. Smekel. Tip-enhanced Raman spectroscopy (TERS) Surface plasmonpolariton enhanced Raman scattering (SPPERS) TERS has been shown to have sensitivity down to the single molecule level and holds some promise for bioanalysis applications.
The single-molecule surface-enhanced Raman scattering (smSERS) has been extensively studied after the initial observation in , yet there still exist unsettled issues in the fundamental mechanism of smSERS. In this review, we survey some of the recent breakthroughs in the mechanism of smSERS and its application. Deterministic Aperiodic (DA) arrays of gold (Au) nanoparticles are proposed as a novel approach for the engineering of reproducible surface enhanced Raman scattering (SERS) substrates. A set of DA and periodic arrays of cylindrical and triangular Au nanoparticles with diameters ranging between 50– nm and inter-particle separations between 25– nm were fabricated by e .

Rodger, in Encyclopedia of Spectroscopy and Spectrometry, Surface enhanced Raman scattering (SERS) was first demonstrated by Fleischmann and colleagues in In a study of the adsorption of pyridine at a silver electrode, they noted that the Raman scattering was considerably stronger when the surface of the electrode was roughened.
Raman scattering is a weak effect. If analyte molecules are adsorbed on a plasmonic metal particle surface, the Raman scattering signal can be enormously enhanced. The effect is then referred to as surface-enhanced Raman scattering (SERS). In extreme cases the enhancement is so strong that even single molecule detection becomes possible.
The solid embedded sections of nanotubes provide single-molecule sensitivity with an enhancement factor up to × for surface-enhanced Raman scattering (SERS). By exploiting the extremely large effective cross sections ( cm2/molecule) available from surface-enhanced Raman scattering (SERS), we achieved the first observation of single molecule.
