Growth and scintillation properties of Eu doped LiSrI3/LiI eutectics

Eu doped LiSrI3/LiI eutectics were grown by the Bridgman method in a quartz ample with 4 mm inner diameter. and their directionally solidified eutectic system has been investigated. Growth rate was 0.3 mm/min. The eutectic showed well aligned eutectic structure and optically transparent. Grown Eu do...

Summary:Eu doped LiSrI3/LiI eutectics were grown by the Bridgman method in a quartz ample with 4 mm inner diameter. and their directionally solidified eutectic system has been investigated. Growth rate was 0.3 mm/min. The eutectic showed well aligned eutectic structure and optically transparent. Grown Eu doped LiSrI3/LiI eutectic shows 400 nm emission ascribed to Eu2+ 4f-5d transition under X-ray excitation. The light yield was around 26,000 photon/MeV for 662 keV gamma-ray and 35,000 photons for 5.5 MeV alpha-ray. •Eu doped LiSrI3/LiI eutectics were grown and their DSE system has been investigated.•Grown eutectic shows 400 nm emission ascribed to Eu2+ 4f-5d transition.•The light yield was around 80% of Ce:Lu2SiO4 (LYSO) standard and 26,000 photon/MeV.•Scintillation decay time under 662 keV ramma-ray was 510 ns.
