CulnSe2 epitaxial films with near stoichiometric compositions have been grown on GaAs (001) by molecular beam epitaxy, and radiative recombination processes in these films have been characterized by means of low temperature photoluminescence (PL) spectroscopy. Temperature dependent PL measurements on such epitaxial films have made possible the identification of conduction band to acceptor and donor-acceptor pair transitions. Well-defined emission lines were present near the bandgap, and the emissions at 1.0386eV and at 1.0311eV were found to be due to the ground-state free exciton and the excitons bound to neutral acceptors, respectively. The bandgap of CulnSe2 is also determined to be Eg=1.0462eV at 2K.
