Surface-enhanced Raman scattering
We present an introduction to surface-enhanced Raman scattering (SERS) which reviews the basic experimental facts and the essential features of the mechanisms which have been proposed to account for the observations. We then review very recent fundamental developments which include: SERS from single particles and single molecules; SERS from fractal clusters and surfaces; and new insights into t...
متن کاملSurface-enhanced Raman scattering
© 2007 American Institute of Physics, S-0031-9228-0711-020-6 When light interacts with matter, it can scatter inelastically from vibrational quantum states. During that process, photons may lose energy to, or gain it from, vibrational excitations. A change in the photon energy must produce a concomitant shift in the frequency of the scattered light (see box 1). The phenomenon, called the Raman ...
متن کاملSurface-enhanced Raman scattering
On the basis of different types of experiments, we develop implicitly the model of surfaceenhanced Raman scattering (SERS) of adsorbates on metal s u r f a c g . The long-range enhancement by resonances of the macroscopic laser and Stokes field is separated quantitatively from the metal eledmn-mediated resonance Raman effect. The latter mechanism proceeds b y increased electron-photon coupling ...
متن کاملSurface-enhanced Raman scattering (SERS) and surface-enhanced resonance Raman scattering (SERRS): a review of applications.
Surface-enhanced Raman scattering (SERS) and surface-enhanced resonance Raman scattering (SERRS) can provide positive identification of an analyte or an analyte mixture with high sensitivity and selectivity. Better understanding of the theory and advances in the understanding of the practice have led to the development of practical applications in which the unique advantages of SERS/SERRS have ...
متن کاملSurface Enhanced Raman Scattering Spectroscopy
This review covers from the basic principles of Raman spectroscopy to the advanced technique of surface enhanced Raman Scattering (SERS) spectroscopy. After briefly going through the description of Raman and introduction of the development of SERS, the article will focus on the “hotspot” of the current research work on SERS – single molecule spectroscopy. We will see later that “hotspot” is als...
