Boron based oxide scintillation glass for neutron detection

摘要

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_2O_3-Li_2O:CeO_2 glass system increased with the increase in B_2O_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.
