An emission band with FWHM of 2.7 meV has been observed at 2.8002 eV. Its emission intensity is proportional to the 1.2 power of the excitation intensity. Excitation spectrum and selective excitation spectrum do not show any additional spectral structure. It is proposed that the origin of this emission is the scattering of excitons by other free particles at a structural defect with slightly lower potential for free particles and free excitons.
