Confined acoustic phonon in CdSC(1-x)Se(x) nanoparticles in borosilicate glass.
We calculate low-frequency Raman scattering from the confined acoustic phonon modes of CdS(1-x)Se(x) nanoparticles embedded in borosilicate glass. The calculation of the Raman scattering by acoustic phonons in nanoparticles has been performed by using third-order perturbation theory. The deformation potential approximation is used to describe the electron-phonon interaction. The Raman-Brillouin electronic density and the electron-phonon interaction are found to increases with decreasing size of nanoparticle. A good agreement between the calculated and reported low-frequency Raman spectra is found.
