Tiivistelmä
Luminescent properties of the ytterbium doped zinc selenide crystals with various concentrations of the doping impurity in 0.03-8 at % range within the temperature interval from 6 K to 300 K were studied. It was shown that ytterbium does not form any proper photoluminescence (PL) bands in the visible spectral range, but it has significant influence on the crystals luminescent properties by changing their defect composition. An attempt to determine ytterbium ion surroundings in the crystal lattice was made based on the obtained experimental results. An assumption about simultaneous compensation of donor and acceptor defects as a result of doping annealing in Zn+X at % Yb melt was made. (C) 2013 Elsevier B.V. All rights reserved.
