Abstract
A theoretical calculation of the differential cross section (DCS) is presented for the exciton-mediated Stokes Raman scattering in CdS quantum dot within the frame work of effective mass approximation at T = 0Â K. Numerical calculations reveal that the excitonic effects cause blue shifts in Raman spectroscopy. The magnitude of the Raman shift depends on the quantum confinement, the Coulomb interaction, and the incident photon energy.
