Evaluation of Scintillation Properties of LiBr:Yb for Thermal Neutron Detection
Scintillation properties of LiBr:Yb synthesized by the vertical Bridgman-Stockbarger method were investigated.Two emission peaks were observed at 415 and 450 nm under X-ray irradiation, which would be attributed to spin-allowed and spin-forbidden 5d-4f transitions of Yb 2+ , respectively.According to pulse height spectra, the highest light yield values (LY) were 3500 photons/neutron and 1900 photons/MeV under 252 Cf neutron and 137 Cs -ray irradiation, respectively, and the / ratio was 0.38.Although the LY was lower than that of the commercial Li-glass scintillator (GS20), the / ratio was comparable to or higher than that of GS20.
