The emission spectrum of exciton complexes formed in individual self-assembled quantum dots (QDs) embedded in a p–n junction is theoretically studied using an effective mass model. We calculate the particle Coulomb interactions, electron–hole overlaps and transition energies of exciton complexes for various strengths and directions of an applied electric field. Both redshifts and blue shifts are observed in excitons, positive and negative trions, and biexcitons. We show that the Stark effect can be used to manipulate the spontaneous emission rate of individual QDs embedded in microcavities.
