Thermal neutron detectors are widely used in a variety of fields, including homeland security, boron neutron capture therapy, and astrophysics. The basic principle of thermal neutron detection is to convert thermal neutrons into low-energy radiation using ³He, ⁶Li,¹⁰B,or¹¹³Cd. In recent years, the use of solid scintillators, including 6Li and 10B, has expanded due to the problem of ³He gas depletion. In this study, in addition to the binary system: Ce1%LaCl₃/⁶LiCl, the ternary system: Ce1%LaCl₃/⁶LiCl /SrCl₂ eutectic was prepared as a new eutectic scintillator, and its crystal phase, luminescent property and scintillator property were also evaluated.
