Abstract :
Mixed BGO-BSO (BGSO) scintillation crystals with structure of eulitine are promising for application in high energy physics (HEP) experiments due to low cost, high density, and reasonable light output. This work is focused on optimization of growth parameters and composition of BGSO mixed crystals. BGSO with improved energy resolution up to 16.2% at 662 keV gamma-irradiation was obtained. The effects of recrystallization and post-growth thermal treatment are discussed.
