چکیده
In this study, a surface-enhanced Raman scattering (SERS) substrate based on an octahedral cuprous oxide (Cu2O) nanostructure to probe methylene blue (MB) molecules as analyte chemical has been implemented. Octahedral Cu2O nanocrystals were synthesized by novel hydrothermal process using only ethylene glycol both reductant and organic solvent. The characteristics of well recognized scanning electron microscope (SEM), X-ray diffraction (XRD), energy-dispersive spectroscopy (EDX), FTIR, spectroscopy. mechanism the SERS surface thoroughly investigated shown involve contributions plasmon resonance charge transfer effects. Using simple collection rule for bands, portion processes was estimated be about 46%.

Directional surface enhanced Raman scattering on gold nano-gratings.
Directional plasmon excitation and surface enhanced Raman scattering (SERS) emission were demonstrated for 1D and 2D gold nanostructure arrays deposited on a flat gold layer. The extinction spectrum of both arrays exhibits intense resonance bands that are redshifted when the incident angle is increased. Systematic extinction analysis of different grating periods revealed that this band can be a...
متن کاملScanned chemical enhancement of surface-enhanced Raman scattering using a charge-transfer complex.
We have fabricated a charge-transfer system using the self-assembly method. We find the nontotally symmetric b(2) modes are selectively enhanced in SERS spectroscopy and represent a laser wavelength-dependent property.
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 ...

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 ...
