Tailoring plasmonic properties of gold nanohole arrays for surface-enhanced Raman scattering.
The wide plasmonic tuning range of nanotriangle and nanohole array patterns fabricated by nanosphere lithography makes them promising in surface-enhanced Raman scattering (SERS) sensors. Unfortunately, it is challenging to optimize these patterns for SERS sensing because their optical response is a complex mixture of localized surface plasmon resonance (SPR) and propagating surface plasmon pola...
متن کاملSurface-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...

© 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 کاملTip-Enhanced Raman Scattering
Background The ability to identify small quantities of adsorbed analyte or structural features down to the few-molecule level is a key challenge in nanotechnology. Optical spectroscopy provides an attractive means to achieve such identification via noninvasive implementations and the potential for chemical sensitivity. Raman scattering has emerged as a particularly powerful technique due to its...
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 ...
