Symmetry of Absorption and Emission Band Shapes of Impurities in Solids
Abstract
Absorption and emission spectra of impurities in solids are calculated quantum mechanically; the lattice-impurity interaction is introduced by a configuration coordinate model. When the vibrational energies of the ground and excited states differ, the spectra are near mirror images at 0K and virtually identical well above 0K. The spacing of the emission transitions differs from that of the absorption transitions, and the intensities are equal to those of the absorption spectrum at an effective temperature that involves the ratio of the excited state vibrational energy and the ground state vibrational energy.
