Abstract

The present interest in the luminescence of II-VI compounds doped by high amounts of Mn is due to the role which the Mn plays in thin film electroluminescence of ZnS:Mn and in the field of semimagnetic semiconductors such as Cd_1-XMn_XTe. In both cases more than one emission band are observed when the amount of Mn passes a lower limit. For Zn_1-XMn_XS this limit is x=0.01 (1). Above this limit emission bands peaking at 1.97, 1.66 and 1.3 eV are registered in addition to the wellknown band peaking at 2.1 eV (⁴T₁(G) → ⁶A₁(S)). Recently Goede et al. tried to explain parts of these bands by octahedraly coordinated Mn²⁺ within local α-MnS domains (2).
