Yb-doped ZnTe layers grown on GaAs substrates have been obtained using mole
cular beam epitaxy. A study of photoluminescence of ZnTe:Yb/GaAs structures
is performed. It is demonstrated that Yb can be rendered optically active
in ZnTe if it is incorporated in three-component complexes which consist of
ytterbium, oxygen, and some of background impurities. (C) 2001 American Va
