Abstract :
The commercial BaFBr:Eu2+·Gd2O3 image plate (IP) is used nowadays for thermal neutron detection. However, it is rather sensitive to γ-ray background, which can deteriorate the image quality. We focused our research on the development of new types of storage phosphors with the general formula M2B5O9Br:Ce3+ (M=Sr, Ca). Neutron detection is based on the 10B(n,α) reaction. The advantages of this system are the low Zeff, and the 40 times higher energy deposition resulting from the neutron capture reaction in comparison with that in the commercial IP. Here we present storage and spectroscopic properties of a series of newly synthesized haloborates. Comparative measurements with commercial IPs were done under neutron and β irradiation. A satisfying light output of optically stimulated luminescence was achieved upon neutron irradiation.
