摘要：
In a previous paper the conventional barrier model of excitonic self-trapping has been shown to display divergencies. In the present work we report on novel 'exotic' exciton-phonon states, which have not been noted so far. These states are of non-self-trapping nature, and by virtue of their small extension in Q-space they may acquire a 'bottleneck' role in the process of energy dissipation. This seems to allow for a new explanation of retarded luminescence. © 1990.
