Resonant raman scattering in CdSxSe1-x nanocrystals : effects of phonon confine...
Freitas Neto, E. S.; Silva, S. W. da; Morais, P. C.; Vasilevskiy, Mikhail; Silva, M. A. Pereira da; Dantas, N. O.Optical phonon modes confined in CdSxSe1-x nanocrystal (NC) quantum dots (≈ 2 nm in radius) grown in a glass matrix by the melting-nucleation method, were studied by means of resonant Raman scattering (RRS)spectroscopy and theoretical modelling. The formation of nanocrystalline quantum dots (QDs) is evidenced by the observation of absorption peaks and theoretically expected resonance bands in the RRS excitation...
