Experimental data on Mn-doped samples of II-VI compounds showed that Mn formed a deep dangling-bond hybrid state that was located at 0.030 to 0.1eV above the valence band. The Mn was present in the [d5 + h)e] H-like state. It was suggested that annihilation of this state might be an intermediate stage in the excitation of intra-center luminescence via the Auger process. Differences between the spectral features of Ni-doped and Mn-doped II-VI compounds could be qualitatively explained by differing mechanisms (tunnelling annihilation and Auger processes) of energy transfer from the H-like state to the intra-center.
