N2 - The coherent and incoherent contributions to the secondary emission of quantum well excitons are calculated microscopically including the combined influence of phonons, photons and structural disorder. Increasing disorder leads to an overall larger signal with shorter rise time. After its initial increase the coherence degree of the secondary emission gradually decays, and even when the initial signal is highly coherent, incoherent components dominate at later times. Since phonon and disorder scattering are closely interrelated, the full secondary emission does not separate into additive contributions from each of the mechanisms.
