The internal relaxation processes of the 3d-center Ni 2~and the recombination of photogenerated holes with Ni-centers are investigated by means of time resolved luminescence spectroscopy of the 3T 1(P)-3T 1(F) Ni 2~transition in ZnS, CdS, ZnSe and CdSe. Ultrafast recombination processes starting at
