Description
In this work we investigated the suitability of newly synthesized series of haloborate phosphors with the general formula M2B5O9X:Ce3+ (M=Sr or Ca; X=Br or Cl) for thermal neutron detection and with reduced sensitivity to γ background. Storage properties such as yield of photostimulated luminescence (PSL) and thermoluminescence are reported. Based on these results the series of the haloborates with 99% enrichment of 10B was sensitized to increase neutron sensitivity. The PSL yields of enriched with 10B haloborates were compared with a common mixture of BaFBr:Eu2+ (40 wt %) and Gd2O3 (60 wt %) under γ and neutron irradiation. The PSL light yield from Ca210B5O9Cl:Ce,Na phosphor after neutron irradiation is 16 times less than that from BaFBr:Eu2+xGd2O3. However, the neutron to γ discrimination of Ca210B5O9Cl:Ce,Na (1%) is almost an order of magnitude better than that of BaFBr:Eu2+xGd2O3. Therefore, haloborate phosphors should be more suitable when utilized in environments with a high γ background
