LiCaAlF₆ crystal is an inorganic scintillator material which is commertialy available for neutron detections. As it is used as a single crystal form, the production cost is high; therefore, our next approach is to investigate LiCaAlF₆:Eu²⁺ ceramics as alternative solutions. In this study, we have synthesized LiCaAlF₆:Eu²⁺ ceramics and characterized as neutron scintillator. Although the scintillation light yield is lower than that of single crysta, the light yield, at best, of 7,600 ph/n has been confirmed.
