Abstract
The luminescence of Sm2+ in alkaline earth berates (BaB8O13, SrB4O7 and SrB 6O10) is reported. The temperature effects on luminescence and decay time o f Sm2+ are studied. Due to the thermal population, D-5(1) --> F-7(J) transi tions of Sm2+ in BaB8O13, SrB4O7 and SrB6O10 are observed at room temperatu re. The f-d broad emission transitions of Sm2+ in SrB4O7 and SrB6O10 are ob served at high temperature whereas no f-d transition is observed in BaB8O13 .
