The temperature of silicon nanoparticles under laser photo-induced heating is determined from the ratio of the intensities of the Stokes and anti-Stokes components of the Raman scattering. The obtained results of the dependence of nanoparticles temperature on the laser radiation intensity and the temperature dependence of the Raman line position maybe used to determine the optimal regimes of photo-hyperthermia enhanced by silicon nanoparticles for cancer therapy.
