Absorption Measurements and Impurity Assignment of Bound Exciton Complexes by Self-Absorbed Luminescence

Abstract
It is shown that self‐absorbed emission lines due to a bound exciton and its phonon satellite may be used to determine (1) the absorption coefficient at the wavelength of bound exciton emission line and (2) the nature of the impurity binding the exciton. The technique is described and is illustrated by experimental results on CdS.
