Abstract
The quaternary semimagnetic semiconductors CdxZnyMnzTe show red and infrared luminescence emission bands which are assigned to the internal transition 4Te1(G) to 6A1(S) within the 3d shell of Mn2+ in different crystalline environments. The intensities and the peak energies of the emission and excitation bands depend upon both the temperature and the ratio x:y. When the Cd ions are replaced by Zn a shift of 30 meV is observed which is small compared with the shift due to replacing the Te anions by S or Se.
