Abstract:New radiophotoluminescence (RPL) phosphate glass containing 6Li was successfully made from the powder of NaPO3, Al(PO3)3, LiOH, HPO3 and AgCl. The ternary diagram of NaPO3Al(PO3)3LiPO3 has clarified the region where satisfactory RPL characteristics of the glass are kept up. The synthesised phosphate glass indicated good RPL characteristics on the condition that the content of LiPO3 was below 10 wt. Gamma-ray irradiation experiments showed that the newly synthesised phosphate glass had satisfactory linearity and wide dynamic range in dose measurement and low variation in sensitivity. It was confirmed from thermal neutron irradiation experiments that a pair of the newly synthesised phosphate glass containing enriched 6Li and 7Li, or nLi and enriched 7Li could be effectively used for the evaluation of thermal neutron dosimetry.
