Abstract :
Characteristics of a SrBPO5:Eu2+ material have been investigated as a neutron storage phosphor. The authors found this phosphor shows photostimulated luminescence by illumination with 635 nm laser light after neutron irradiation. The neutron sensitivity was proportional to E-0.5, where E is neutron energy. The Sγ/Sn ratio of the phosphor using enriched boron was better than that of a commercially available imaging plate, where Sγ and Sn are the gamma and neutron sensitivities, respectively. A collimated neutron beam image was clearly obtained with the phosphor sample by scanning focused laser light on it.
