dc.description.abstract | The evolution of the optical phonon spectra of colloidal core/shell CdSe/ZnS quantum dots with an increase
of the shell thickness from 0.5 to 3.4 monolayers has been studied by resonant Raman spectroscopy. The
results obtained suggest that the ZnS shell changes its structure from amorphous to partly crystalline as the
thickness increases. Simultaneously, an increase in Raman scattering by surface ~core/shell interface! phonons
and the redshift of the corresponding phonon band have been observed and assigned to variations in the shell
structure. The disorder present in the shell provides a major contribution to the line shape of the Raman spectra
at higher ZnS coverage. A method to control the quality of quantum dots based on Raman spectroscopy is
proposed. | en |
