RBPO$$_{5}$$(R=Ca, Sr)-based storage phosphors for neutron detection

Sakasai, Kaoru  ; Katagiri, Masaki; Matsubayashi, Masahito  ; Nakamura, Tatsuya  ; Kondo, Yasuhiro*

Storage characteristics of RBPO$$_{5}$$(R=Ca, Sr) based phosphors have been investigated for neutron detection. To increase the photostimulated luminescence (PSL) yields of CaBPO$$_{5}$$:Ce$$^{3+}$$ and SrBPO$$_{5}$$:Ce$$^{3+}$$ phosphors, fluorine atoms were introduced and the molar ratio of the fluorine atoms was optimized for the PSL yields. In addition, the authors found that the PSL yields of SrBPO$$_{5}$$:Eu$$^{2+}$$ phosphors were significantly increased by adding Li$$_{2}$$B$$_{4}$$O$$_{7}$$, though introducing fluorine and brome atoms in the phosphor was not effective for the PSL yields. These phosphors will be usable as new neutron storage phosphors with low $$gamma$$-ray sensitivity because they consist of light materials.
