Data on position and lifetime of the photoluminescence band in Cd 1− x Mn x Te and Zn 1− x Mn x Te are reported for different manganese concentrations x . The luminescence is due to intraatomic transitions within the manganese ions. The blue shift at low temperatures shows the typical behavior of an exchange dependent parameter. The lifetimes are in the microsecond range. At low temperatures the decay is dominated by the radiative lifetime with weak temperature dependence. In Zn 1− x Mn x Te the lifetime varies with manganese concentration, whereas in Cd 1− x Mn x Te the concentration dependence is insignificant.
