Ce-doped LiF–SrF2 eutectic scintillators for thermal neutron detection produced at different solidification rates

A novel LiCl–BaCl2:Eu2+ eutectic scintillator for thermal neutron detection

“…1(d) and (e). It shows the lamellar structure of the eutectic, similar to the structure reported for Eu-doped LiF-CaF 2 [10] and Ce-doped LiF-SrF 2 [12] eutectics. The phases are elongated along the pulling direction.…”

“…This result demonstrates the feasibility of large-size eutectic scintillator growth by using the Bridgman method. In the following years, several fluoride-based eutectics were developed, including LiF-SrF 2 and LiF-CaF 2 [11], Ce 3 þ -doped LiF/CaF 2 [12], Ce 3 þ -doped LiF/LiYF 4 [13] and Ce 3 þ -LiF/LiLuF 4 [14]. The neutron induced absolute light yield of LiFSrF 2 has already reached 9400 ph/neutron, which is higher than that of Li-glass [11].…”

Inorganic scintillating materials and scintillation detectors

“…The most common materials are BaF 2 , 48) SrF 2 , 49) CaF 2 50) and their mixed compounds. 51,52) Common properties of STE are a broad emission peak in the emission spectrum, a large Stokes shift, a relatively high light yield in scintillation, a relatively fast decay time from several hundred ns to few µs and a large temperature dependence of the scintillation light yield.…”

Optical and Scintillation Properties of Pure ZnS Crystal

“…The optical grease was used to the optical contact with the PMT and several layers of Tefron tapes were used to wrap the scintillator as a reflector and there was a pinhole with 1 mm for 241 Am-ray irradiation. The data flow was reported previously [12].…”
