Abstract
Optically detected magnetic resonance experiments have been used to study the broad emission bands from iodine transported mixed crystals of ZnSxSe1-x for x=0.85, 0.40, 0.10 and 0.00, for which donor to acceptor recombination involving A-centres is found to occur. The different self-activated emission bands are attributed to A-centres involving different configurations of neighbouring sulphur or selenium ions. The highest-energy band results from recombination at a (VZnS3) A-centre whilst recombination at A-centres in which the zinc vacancy has selenium neighbours results in emissions at lower energies.Keywords
