Abstract

The exciton mechanisms of energy transfer to luminescence centers in alkali and alkali earth halides considered in the present paper are: (1) resonance transfer from self-trapped excitons to distant centers: (2) jump diffusion of axially relaxed excitons; and (3) migration of excitons before the axial vibrational relaxation. The last process is facilitated in iodides, because the relaxed state is achieved after surmounting an energy barrier.
