摘要：

Radiationless transitions can be classified either as static processes which proceed from thermal equilibrium or dynamic processes which occur during rapid relaxation. Theoretical descriptions of both processes are surveyed and assessed, following discussion of physical principles. Cited examples of static processes include thermal ionization of F centers and thermal quenching of fluorescence of rare-earth and transition-metal impurities. Dynamic processes are exemplified by athermal fluorescence quenching in color centers, recombination-enhanced defect reactions in semiconductors and insulators, and intersystem crossing in transition-metal impurities. © 1990.
