Abstract:On the basis of the studies carried out, it is shown in the work that the influence of oxygen on the optical properties of AIIBVI crystals is determined by three main effects. This is the formation of a system of bound excitons accompanying the presence of high oxygen concentrations at stacking faults --- a long-wavelength shift by hundreds of meV of the absorption edge, and the third effect is determined by the emergence of broadband "self-activated" SA luminescence in the near-edge region of the spectrum.
