Abstract
Heavy halogen ions substitute easily in alkali halide crystals and even form dimers and trimers... with increasing concentration and finally gather into clusters. This effect has mainly been investigated by the observation of the change in the shape of the absorption bands [1] which appears in the tail of the fundamental absorption of the host crystal in the ultraviolet range. This has been interpreted as a localized exciton. This effect has been confirmed by emission spectra recorded with an excitation at the localized exciton energy.
