The occurrence of different Mn centres in single crystals of ZnSe and ZnS as well as in ZnS powder is reinvestigated. Besides the well-known centres of single crystals a new axial Mn2+ centre in ZnS is observed, and the formation of Mn2+–Mn2+ pairs is detected not only for ZnS but also for ZnSe. The influence of a Mn doping on the crystalline modification of ZnS powder is proved. Mn2+ centres on cubic and hexagonal sites as well as ones in faulted regions are detected. For the first time EPR results of Mn centres in thin-film structures of ZnS and ZnSe are presented.
