Abstract

Abstract Sr co-doped Ce:LiCaAlF 6 [Ce:Li(Ca,Sr)AlF 6 ] crystals with various Ca/Sr ratios were grown by a micro-pulling-down (μ-PD) method and effects of Sr co-doping on crystal structure, chemical composition, optical and scintillation properties for Ce:LiCaAlF 6 crystals were investigated as a neutron scintillator. High transparent Ce2%:Li(Ca,Sr)AlF 6 crystals with 2% and 5% Sr contents were obtained while Ce2%:Li(Ca,Sr)AlF 6 crystals with 10% and 20% Sr contents included milky parts in the crystals. a - and c -axis lengths of Ce:Li(Ca,Sr)AlF 6 phase systematically increased with an increase of Sr content. In addition to the emission at 284 and 308 nm from Ce 3+ ion, emission peaks at 367 nm appeared by Sr co-doping.
