- Аннотация: Photoluminescence properties of barium thio- and selenogallates doped with Eu2+, Ce3+ and co-doped with Eu2+ and Ce3+ were studied in a temperature range of 10-300 K and an optical excitation intensity interval of 3 x 10(-4) - 1.25 x 10(6) W/cm(2). Barium thiogallates doped with europium and co-doped by both rare-earth elements show a high thermal stability of the luminescence characteristics and significantly exceed the selenogallate analogues in respect of photoluminescence efficiency. Both thio- and selenogallates activated with the rare-earth elements demonstrate a considerable PL efficiency droop only at high excitation levels exceeding 20 and 10 kW/cm(2), respectively. Possible reasons of the droop mechanisms are discussed. (C) 2011 The Japan Society of Applied Physics
