Raman spectroscopy of Cd1-xMnxS quantum dots
Abstract
Powders consisting of 44 angstrom Cd1-xMnxS (x = 0; 0.05; 0.1; 0.15; 0.3) quantum dots (QDs) were synthesized using the colloidal chemistry method and characterized by Raman scattering measurements. The dominant Raman line of the 44 angstrom Cd1-xMnxS QDs was at about 300cm(-1) showing asymmetric broadening for omega LT 300cm(-1). A significant change in the intensity of the first harmonic for different x and excitation energies was noticed. Also, the second harmonic of confined Raman modes was experimentally observed. A theoretical model was used to calculate the relative contributions of the confined Raman scattering modes for the 44 angstrom US QDs and satisfactory agreement with experimental results was found.
