This book was released on 1984 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ag colloids with adsorbed CN( - ) complexes, pyridine, and HSO3( - )/SO3(2- ) ions are prepared and characterized by their elastic scattering spectra, extinction spectra, and particle size distributions. Enhanced Raman spectra from these colloids are measured as a function of incident laser wavelength over the 423-676.4-mn range. The maximum in the excitation profile for the Raman scattering shifted to a longer wavelength than that for the elastic scattering and extinction profiles. Furthermore, the Raman excitation profile peaked at a longer wavelength than that predicted by the electromagnetic calculations for the field at the tips of and surface-averaged over isolated spheres of various radii. The effect of colloid aggregation on the SERS intensity of CN( - ) complexes adsorbed on the Ag colloids is discussed. Originator-supplied keywords include: Wavelength; Raman scattering; Colloids; Silver colloids.

Available in PDF, EPUB and Kindle. Book excerpt: The surface enhanced Raman scattering spectra of crystal violet and R6G and a number of colourless molecules adsorbed on silver colloid aggregates were studied as a function of power and position using a Raman microscope. The anti-Stokes signals of the dye molecules show line intensities much greater than the expected on the basis of the Boltzmann equilibrium population of the excited vibrational state. The large anti-Stokes intensities are attributed to the difference in Stokes and anti-Stokes Raman cross-sections resulting from pre-resonance or resonance Raman processes in the adsorbate-substrate complex rather than to optical pumping of molecular vibrational excited states as proposed by Kneipp and co-workers [Phys. Rev. Lett., 76, 2444, 1996]. Far-field imaging with a Raman microscope shows no significant inhomogeneity of the Raman enhancement in the images of the deposited self-affine silver colloid clusters down to spatial resolutions of I [mu]m2. A near-field scanning optical microscope (NSOM) operating with a shear-force feedback distance-control mechanism was employed to study the optical response of self-affine, deposited colloidal silver films. In the near-field region, NSOM is capable of an optical resolution down to 100 nm which is beyond the traditional diffraction limit of far field optics. Near-field Rayleigh microscopy with simultaneous topographic imaging indicates that the electromagnetic fields on the surface of the self-affine films are localized in regions smaller than the excitation wavelength. The pattern of high-field regions varies greatly with excitation wavelengths and does not correlate with topography. Local spectra of self-affine film showed distinct resonances arising with highly location-dependent frequencies. The most highly resolved of these resonances correspond to individual surface plasmon normal modes. Specific vibrational bands from the SERS spectra of plithalazine adsorbed on self-affine, silver colloid films were mapped over portions of the film surface in the near-field. The near-field Raman intensity maps display patterns of field localization in subwavelength regions. The pattern of field localization varies greatly with scattered wavelength. Observations in the near-field validate recent theories of the optical response of self-affine fractal objects [Phys. Report, 61, 272, 1996].
