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.

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 .

Tsukuba Satellite Symposium on Single Molecule and Tip-Enhanced Raman Scattering. “1-molecule-Raman spectrum” is generated by the same molecule and that all properties of the spectrum are a function of the individual properties of this molecule. Figure 1 shows surface-enhanced Raman scattering (SERS) spectra measured in time sequence from a scatter-ing volume which contains an average of crystal violet Size: KB.

The focus is on the recent trend of combining tip-enhanced Raman scattering microscopy with various external stimuli such as pressure, voltage, light, and temperature, which enables the local control of the molecular properties and functions and also enables chemical reactions to be induced on a nanometer : Yano Taka-aki, Hara Masahiko.

The single-molecule surface-enhanced Raman scattering (smSERS) has been extensively studied after the initial observation inyet 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 by: Surface- and tip-enhanced Raman spectroscopy (SERS and TERS) techniques exhibit highly localized chemical sensitivity, making them ideal for studying chemical reactions, including processes at catalytic surfaces.

Catalyst structures, adsorbates, and reaction intermediates can be observed in low quantities at hot spots where electromagnetic fields are the strongest, Cited by: MACCALL, PLATZMAN and WOLFF[1], KERKER, WANG and CHEW[2] and WANG and KERKER[3] in fact showed that a molecule adsorbed on a metal sphere can yield a giant Raman signal, 10 5 times as strong as that from a free molecule, through the excitation of surface plasmon polaritons.

Here we introduce a tool for the correlative nanoimaging of EM and SERS hotspots, areas of strongly enhanced EM fields and Raman scattering, respectively.

To that end, we Cited by: W.E. Smith, C. 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.

It is particularly remarkable that the hyper-Raman signal from one molecule can be stronger than the second harmonic generation from a complete.
