The properties of ZnS(Ag)/6LiF samples with three different mass ratios were studied. The study showed that the EJ426 sample with the mass ratio of 3:1 had the highest detection efficiency of thermal neutrons, which was 32.4% in the experiment. Furthermore, this sample had the largest charge spectrum. The light yield of its surface at the average value of the charge spectrum was approximately 8.01 × 103 photons/neutron. The gamma sensitivity of the sample was better than 10−6 at the threshold of 350 photoelectrons. Therefore, EJ426 is a good candidate for a position-sensitive thermal neutron detector.
•Three ZnS(Ag)/6LiF samples with different mass ratios were studied.•EJ426 sample has higher detection efficiency and light yield.•EJ426 has the best γ sensitivity and light output in the samples.•EJ426 is the best choice for a positive-sensitive neutron detector in the samples.
