Abstract
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 0.60–0.90mm/min. In the eutectics, Ce3+ 4f–5d emission was observed at 410nm. The eutectics showed light yield of around 300photon/5.5meV alpha-ray by 241Am excitation. Scintillation decay time was 26.4ns (45%) with slower decay component of 263ns (55%).
