Abstract

We report on spin-flip Raman scattering and on Raman scattering by acoustic phonons in CdS nanocrystals embedded in a glass matrix. We discuss both the spin-flip and the acoustic-phonon Raman spectra on the basis of the interaction of size-quantized electronic excitations with nonconfined acoustic vibrations. The polarization of spin-flip Raman scattering in the Faraday and Voigt configurations is analyzed in comparison with that for bulk CdS. The effective electron (Formula presented) factor has been measured as a function of the quantum dot size.
