Abstract Thermal neutron detection is a key subject for nuclear physics research and also in a wide variety of applications from homeland security to nuclear medicine. In this work, it is proposed a novel flexible and conformable composite thermal neutron scintillator based on a fully enriched Lithium Tetraborate preparation ( $$^{6}$$ 6 Li $$_2^{10}$$ 2 10 B $$_4$$ 4 O $$_7$$ 7 ) combined with a phosphorescent inorganic scintillator powder (ZnS:Ag), and is then distributed into a polydimethylsiloxane matrix. The proposed scintillator shows a good neutron detection efficiency (max. $$\sim$$ ∼ 57% with respect to the commercial EJ-420), an average light output of $$\sim$$ ∼ 9000 ph/neutron-capture, a remarkable insensitivity to $$\gamma$$ γ -rays (Gamma Rejection Ratio
