Abstract
The radiative decay of excitons in thin films is studied. The exciton modes capable of radiating are found to be superradiant, in contrast to the case of excitons in a bulk crystal. It is estimated that this radiative decay mechanism will dominate over the other decay mechanisms such as those due to phonons or lattice imperfections.Keywords
