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 0.60-0.90 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%).
