A ⁶LiCl/⁶Li₂SrCl₄ eutectic scintillator with a high Li concentration was developed as a novel thermal neutron scintillator. Eu²⁺ served as an activator for the ⁶Li₂SrCl₄ phase, and Eu-doped ⁶LiCl/⁶Li₂SrCl₄ eutectics were grown via the Bridgman Stockbarger method in quartz ampoules (inner diameter = 4 mm). The Eu-doped ⁶LiCl/⁶Li₂SrCl₄ eutectics exhibited a lamellar-type eutectic structure and optical transparency, as well as 400 nm emission due to Eu²⁺ 5d-4f transition. The scintillation properties of the eutectics were evaluated under gamma- and alpha-ray irradiation to demonstrate its potential as a thermal neutron scintillator.
