Abstract

We fabricated neutron detection glasses, Tb³⁺-doped CaO–Al₂O₃–B₂O₃ glasses, including ¹⁰B-enriched (¹⁰B glass) and ¹¹B-enriched (¹¹B glass) glasses. The glasses were irradiated with X-rays, heavy particles, or neutrons and their thermoluminescence (TL) properties were investigated. The TL properties after X-ray or heavy particle irradiation were the same for the ¹⁰B and ¹¹B glasses. Meanwhile, after neutron irradiation, the TL properties of the ¹⁰B and ¹¹B glasses were significantly different. The TL intensity of the ¹⁰B glasses was higher than that of the ¹¹B glasses, and the TL peak intensity of ¹⁰B (n, α) reaction had good linearity in the irradiation range of 10⁹–10¹³ neutrons/cm².
