The cathodoluminescence spectra for Cd_{1-x}Μn_{x}Te (0 < x ≤ 0.7) and Zn_{1-x}Mn_{x}Te (0 < x ≤ 0.6) at room and liquid nitrogen temperature have been presented and discussed. Especially, the influence of increasing temperature and Mn content on cathodoluminescence spectra. The cathodoluminescence emission in Ζn_{1-x}Mn_{x}Te (Cd_{1-x}Μn_{x}Te) centered at ≈ 1.95 eV (2.0 eV) and ≈ 2.2 eV (2.5 eV) are ascribed to Stokes-shifted ^{4}Τ_{1}(^{4}G) → ^{6}A_{1}(^{6}S) and ^{4}Τ_{2}(^{4}G) → ^{6}A_{1}(^{6}S) internal transitions of Mn^{+2} within the 3d^{5} state, respectively.
