| Research Abstract |
A Raman scattering spectrometer has been developed for characterizing visible-light sensitized photocatalysts. When the incident photon energy is resonant to an electronic transition of the object, Raman scattering probability is enhanced by 104times or more. This resonance enhancement is well known and intentionally used in characterizing colored solutes or labeled biomaterials in liquid. In the present study, the lattice vibration of sulfur- or nitrogen-doped TiO_2 photocatalysts are examined using 442 nm light for excitation to be in resonance with the dopant-induced electronic transition.
