Abstract

It is shown that the optical activation of Yb in GaAs and low-dimensional GaAs/GaAlAs structures can be achieved by forming three-component (Yb+S/Se/Te+O) luminescence centers based on the Yb3+ ion. A correlation between the characteristics of these centers and the parameters of the chalcogen coactivators is discovered. Oxygen is shown to play a decisive role in transferring the energy of electron-hole pairs to the luminescence centers.
