Experimental studies of X‐ray photoelectron and Co L α X‐ray emission spectra of the ZnS:Co semiconductor were carried out. It was established that Co ions are in a Co 2+ configuration and that the Co 3 d impurity states are localized above the top of the valence band by 1.0 ± 0.2 eV. It was found that the covalency reduction factor for Co 2+ defect changes through the alloy from 0.62 in ZnSe lattice to 0.59 in ZnS. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
