Abstract
Time dependences of the photon echo in nanocrystals are theoretically considered under conditions of simultaneous coherent excitation of sev eral excitonic levels for strong and intermediate confinement. A simpl e model is used to take into account the influence of strong electron- phonon coupling. Results of calculations for situations when quantum-s ize excitonic levels manifest themselves in experiments are presented.
