Luminescence and scintillation properties of Ce dope SrHfO3 based eutectics

• Ce doped SrHfO3/SrAl12O19 eutectics were grown by the micro pulling down method and submicron-diameter phase-separated scintillator fibers has been observed in the eutectics.
• The Ce3+ 4f–5d emission was observed at 410 nm.
• The eutectics showed light yield of around 300 photon/5.5 meV alpha-ray by 241Am excitation.
• Scintillation decay time was 26.4 ns (45%) with slower decay component of 263 ns (55%).

Ce doped SrHfO3/SrAl12O19 eutectics were grown by the micro pulling down (μ-PD) method and their directionally solidified eutectic system has been investigated. Investigations of obtained eutectic structure, luminescence and scintillation performances were also performed. Eutectics were grown at the speed of 0.60–0.90 mm/min. In the eutectics, Ce3+ 4f–5d emission was observed at 410 nm. The eutectics showed light yield of around 300 photon/5.5 meV alpha-ray by 241Am excitation. Scintillation decay time was 26.4 ns (45%) with slower decay component of 263 ns (55%).
