It is established that the doping of ZnSe:Al crystals with ytterbium from the vapor phase brings about the appearance of two new bands in the low-temperature luminescence spectra. Emission in the energy range 1.15–1.35 eV is defined by transitions in Yb^3+ ions, and the edge band is defined by the LO-phonon-assisted transitions of free electrons to acceptor levels of uncontrollable Li impurities.
