A fully quantum-mechanical theory for the spontaneous light emission from the interacting electron-hole system in a quantum dot is developed. Using a cluster-expansion approach, a closed set of equations of motion for singlets and two-particle correlations is derived. Photoluminescence spectra are calculated and the radiative decay dynamics is discussed.
