Abstract
AbstractRaman scattering by surface phonons in CdS1–x Sex nanocrystals grown in a borosilicate glass matrix, is studied. CdSe‐like and CdS‐like surface phonon frequencies are shown to increase with the relevant component content in the nanocrystal composition. No clear size dependence of the surface phonon frequencies has been observed. On the other hand, surface phonons in CdS1–x Sex nanocrystals exhibit resonant dependence on the Raman excitation wavelength. It is emphasized that measurements of Raman scattering by surface phonons in CdS1–x Sex nanocrystals give no reason to judge upon the nanocrystal shape. (© 2009 WILEY‐VCH Verlag GmbH & Co.
