Abstract
Near-infrared photoluminescence (PL) has been studied in CuGaSn2, AgGa Se2 and AgGaS2 crystals doped with Yb. Sharp PL lines are observed in the 1.0 mu m region for these crystals. These PL lines are assigned to F-2(5/2) --> F-2(7/2) transition of the spin-orbit split states of th e Yb3+ ion in the chalcopyrite crystal lattice.
