Fundamentals of Radiative Transitions of Ions and of Ion Pairs in Solids
The interaction “between radiation and ions in solids is analyzed semiclassically. The ions in the solids are treated quantum mechanically; the radiation, classically. Electronic transitions induced by time-dependent perturbations are considered generally and then the transition matrices for electromagnetic radiative transitions are determined. These transitions are related to the Einstein induced and spontaneous transition probabilities. Cooperative phenomena at high radiation densities are noted. Finally, the effects of irreversible phonon relaxation processes are considered.
