The sensitivity for neutrons and γ-rays of europium-doped BaFBr, KCl and KBr storage phosphors with various fractions of the neutron converters natLiF and GdF3 was evaluated in order to find a system with a high neutron-to-γ (n/γ) ratio. The highest photostimulated luminescence (PSL) after neutron exposure of all Gd-containing samples was measured for a sample containing 35 mol % GdF3, while for all LiF-containing samples a maximum was found at 70 mol % LiF. The use of LiF instead of GdF3 results in a higher n/γ ratio due to a higher PSL output per absorbed neutron. The highest n/γ ratio was measured for the system KCl:Eu2+-LiF, indicating a very attractive material for neutron-image plates when utilised in environments with a high γ-background.
