　　In this decade,some novel inorganic scintillators for neutron detection have been reported.Among them,LiCaAlF6 based scintillator is the most promising candidate.LiCaAlF6 includes Li in the host lattice and have a function of the pulse shape discrimination between neutrons andγ-rays[1].It is single crystal and Li content is determined by the chemical formula.Thus,if we need higher neutron detection efficiency by Li,other materials become also a candidate.In this study,as a canditate for novel neutron detectors,Eu activated LiF-LiCaAlF6 eutectic scintillators were grown by micro-pulling-down method and their scintillation properties under 252Cf neutron exposure were examined.The most important advantage of this eutectic scintillators is higher Li content than that of conventional neutron scintillators like Li-glass,Eu:LiI,LiFIZnS.
