Description

We investigate the Stokes to anti-Stokes intensity ratio in the phonon Raman spectra of rutile titanium dioxide (TiO2). The frequency dependence of the ratio for first-order scattering shows a plateau where the ratio does not vary with frequency near the peak frequency of Eg mode, while the second-order component satisfies the relation of the Boltzman factor. The frequency region of the plateau broadens with temperature, and it is suggested that the irreversible relaxation that broadens the phonon energy plays an important role. (author)
