Abstract

Eu²⁺ 0.05%, 0.1%, and 0.2% activated LiF-SrF₂ eutectic scintillators were prepared by the Bridgman method using ⁶Li enriched (95%) raw material. The α-ray-induced radio luminescence spectra showed intense emission peak at 430 nm due to an emission from Eu²⁺ 5d-4f transition in the Eu:SrF₂ layers. When excited by ²⁵²Cf neutrons, all the samples exhibited almost the same light yields of 5000-7000 ph/n with a typical decay times of several hundreds ns.
