LiF/CaF2/LiBaF3 ternary eutectic scintillators were grown by the μ-PD method. In the solidified eutectic the phases were uniformly distributed in the transverse direction and aligned along the growth direction. For the Eu-doped samples, the expected emission peak observed at 425nm was ascribed to Eu2+ 5d-4f transition from Eu:CaF2 under X-ray excitation. The LiF/CaF2/LiBaF3 ternary eutectic scintillators showed a light yield around 7,000 photons/neutron and decay time of 260 ns (73.6%) and 50 ns (26.4%).
