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 -ray sensitivity because they consist of light materials.
