  • Publication number: 20190170651
    Abstract: A needle-shaped body protrudes from a cantilever made of Si. Furthermore, the rear face of the cantilever is coated with aluminum having a Fermi level higher than that of Si. The cantilever is dipped into an aqueous silver nitride solution containing the ions of Ag serving as a second metal. The electrons of Si flow out to the aqueous silver nitride solution due to the existence of the aluminum, and Ag nanostructures are precipitated at the tip end of the needle-shaped body. A probe for tip-enhanced Raman scattering in which the Ag nanostructures are fixed to the tip end of the needle-shaped body is manufactured. The sizes and shapes of the Ag nanostructures can be controlled properly by adjusting the concentration of the aqueous silver nitride solution and the time during which the cantilever is dipped into the aqueous silver nitride solution.

  • Patent number: 8964175
    Abstract: Distribution is acquired for a reflectance spectrum and a fluorescence emission spectrum on a sample composed of color-image recorded matter. Then, on the basis of the distribution of the reflectance spectrum and the fluorescence emission spectrum, a single color portion is identified that is generated with one colorant selected from colorants of plural colors used in generating a color image. A control unit stores in advance Raman spectra of colorants of single color for each manufacturer. Laser light is projected onto the single color portion of the sample so that a Raman spectrum is measured. Then, the measured Raman spectrum is compared with the Raman spectra stored in advance so that the manufacturer of the colorant is identified and hence the colorant is identified.

  • Patent number: 8102524
    Abstract: Laser light having an energy of 1.9±0.1 eV is projected onto a carbon nanotube-containing substance so that a Raman spectrum is acquired. On the basis of the intensity of a peak at Raman shift 221±5 cm?1 caused by aggregates of single-walled carbon nanotubes, the degree of dispersion of single-walled carbon nanotubes in the carbon nanotube-containing substance is determined. A lower intensity of the peak indicates a higher degree of dispersion in the carbon nanotube-containing substance. As such, when the intensity of a particular peak contained in a Raman spectrum is measured, the degree of dispersion of single-walled carbon nanotubes in a carbon nanotube-containing substance can be evaluated easily and clearly.
