Recombination luminescence is stimulated with red-infrared light in NaI which has been exposed previously to ultraviolet radiation in the low-energy tail of the fundamental absorption spectrum. This stimulated luminescence was undetectable below approximately 65 K and was found to have an activation energy of 0.06±{}0.01 eV. Evidence is presented which suggests the thermal dissociation of free excitons.
