Abstract

Photoluminescence properties of barium thio- and selenogallates doped with Eu²⁺, Ce³⁺and co-doped with Eu²⁺ and Ce ³⁺were studied in a temperature range of 10-300 K and an optical excitation intensity interval of 3 × 10^-4-1:25 × 10 ⁶ W/cm². 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 efficiencydroop only at high excitation levels exceeding 20 and 10 kW/cm², respectively. Possiblereasons of the droop mechanisms are discussed.
