The cathode- and x-ray luminescence spectra for CdS(O) crystals with the known oxygen concentration, CdS band gap dependence on [O] and the zone model built based on the theory of «band anticrossing-BAC» have been studied. The new data have been obtained for three types of the CdS self-activated luminescence: edge emission, SA and F centers. The conditions of appearance of these centers luminescence as a result of the change of CdS intrinsic point defects in presence of oxygen have been explained.
