Surface-enhanced Raman length

Because macroporous materials have 3D periodicity on a length scale comparable to the wavelength of visible light, 3DOM materials have potential use as photonic crystals. Other potential applications include catalysts, bioglasses, sensors, and substrates for surface-enhanced Raman scattering spectroscopy (SERS). ... [Pg.5675]

The interactions with the surface and reaction kinetics have been studied in detail using various techniques, such as voltammetry, electrorefiectance measurements and surface enhanced Raman spectroscopy [139,140]. For monolayers on gold assembled from long chain thiols of the structure HS-(CH2) -C00H (with n > 9) the interfacial electron transfer rate exponentially decreases with chain length and the tunnelling parameter is in the... [Pg.283]

On Ag sols, molecules lie mainly fiat on the surface, as determined from SERS (surface enhanced Raman spectroscopy) measurements. However, the molecules are twisted and there is evidence for a small inclination against the surface. The twisting decreases and the inclination increases with increasing chain length [10-12]. The observed twisting of the molecules is in line with crystal powder X-ray diffraction data (see, e.g., [13] and references therein) which show a small twisting angle (3 -12 ) between the monomeric units in the solid state of 3T [14] and 4T [15,16]. 2T... [Pg.680]

On Ag sols molecules lie mainly flat on the surface, as determined from SERS (surface enhanced Raman spectroscopy) measurements. However, the molecules are twisted and there is evidence for a small inclination against the surface. The twisting decreases and the inclination increases with increasing chain length [151-153]. [Pg.223]
