Evolution of the CdS/TiO 2 Raman spectra upon simultaneous variation of the laser power and acquisition time (irradiation dose remains constant). The inset shows the variation of the intensity ratio I(LO)CdS/I(E g)TiO2 determined from the integrated areas of the CdS LO mode and the E g anatase TiO2 mode, with the spectral acquisition time.
