Abstract

Formula is presented to evaluate the second order optical response in the exciton-phonon complex with the aid of the multiple-scattering expansion of the tetradic propagators. The emission spectrum due to the exciton shows that the luminescence component is strongly influenced by the transfer of the exciton. The mobile nature of the exciton brings about the rapid relaxation of the exciton due to the interaction with the reservoir and reduces the intensity of the Raman component even in the case of the incident photon frequency Q above the fundamental absorption edge. These weak Raman lines recover their intensity when is chosen below the edge. It is suggested that the freedomof the choice of Qj is advantageous in investigating the competitive behavior of the Raman and the luminescence components in the emission spectrum.
