Boron based oxide scintillation glass for neutron detection

Abstract The luminescence property of Ce-doped oxide glass having B and Li with large absorption coefficient for neutron was investigated by optical transmittance, alpha particle, and neutron irradiation. The light output of the B 2 O 3 –Li 2 O:CeO 2 glass system increased with the increase in B 2 O 3 and CeO 2 . It was observed that the decay time which showed composition dependence varied in the range 30–45 ns. Although the light output by neutron irradiation is 9.2% of Li-glass, low density and high neutron absorption with short decay time make this new boron-based glass scintillator useful for neutron detection.
