Abstract

The luminescence spectrum of ZnS crystals — both undoped and doped — in the visible consists of wide bands. The crystals cooled to liquid He temperature were excited by a mercury lamp or a nitrogen laser, and the spectra were measured by “modulation spectroscopy”. Structure was found in the wide bands and attributed to donor-acceptor pair transitions and their phonon replicas. The dependences of emission spectra on temperature and on excitation intensity are explained, in terms of changes in occupation of conduction and donor states.
