Abstract
Based on new results of transmission and emission experiments on CdS single crystals in a very extended range of excitation intensities at 1.8 K, we discuss the annihilation and formation of excitonic mole cules in a model involving AΓ6-excitons and AΓ5-polaritons. It is shown that the presented results as well as those by Saito and Shionoya can be consistently explained in this model. A theoretical foundation of the model and a way to calculate emission and absorption spectra due to excitonic molecules are presented.KeywordsExcitation IntensityEmission ExperimentDominant LineEnergetic PositionGround State ExcitonThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
