Research Abstract

Now, advanced researches with strong quantum beams make progress in the world. Inthis study, we focused on the photo-stimulable phosphor of Ag-zeolites which are consist ofrelatively light elements and have storage and ion-exchange capacities, in order to developa photo-stimulabe phosphor for a strong neutron field. We made Ag-zeolites stored neutronconverters such as boron or lithium, and investigated their optical properties. Furthermore,neutron irradiation measurements were performed to investigate the optical properties for neutrons.
