Abstract

In this study, we fabricated Dy3+-doped Li2O–Al2O3–B2O3 glasses using 6Li or nLi and 10B or 11B (6Li–10B, 6Li–11B, nLi–10B, and nLi–11B glasses) to develop a new thermoluminescent material for neutron detection, and their thermoluminescence (TL) properties were investigated after X-ray and thermal neutron irradiation. TL glow peaks were observed at 370 K after X-ray irradiation, and the integral values of TL intensities from 350 to 390 K for 6Li–10B, 6Li–11B, nLi–10B, and nLi–11B glasses were similar, indicating that these glasses have similar sensitivities to X-rays. A TL glow peak was observed at 400 K after neutron irradiation, and the integral values of TL intensities from 380 to 420 K for 6Li–10B, 6Li–11B, and nLi–10B glasses were higher than those of the nLi–11B glass, indicating that γ-rays and high-energy particles generated in the 6Li(n, α)3H and 10B(n, α)7Li reactions efficiently induced TL. The TL intensity of the 6Li–11B glass was significantly higher than those of the other glasses and showed good linearity against the thermal neutron fluence in the range of 5 × 107–1011 neutrons cm−2.
