Paper Abstract

Characteristic scattering band in the spectral region of 280-380 nm with the maximum of 300-310 nm is observed in the spectra of diffuse scattering for rutile, contrary to anatase sample. Spectral parameters of this band depend on the treatment temperature. Doping of Ti02 samples with Cu, Fe, Co, Cr atoms does not affect the spectral position of the band wing in their diffuse scattering. Luminescence spectra of rutile have only short-wavelength components. Anatase has both fluorescence and phosphorescence at T=4.2 K. At room temperature there is no luminescence detected. Cation-doped anatase does not luminescence at all studied temperatures. Their absorption spectra have a new band in the region of 325-405 nm, which spectral parameters depend on the type ofdoping cation.
