Abstract

We fabricated neutron detection materials based on Dy³⁺-doped CaO–Al₂O₃–B₂O₃ glasses, including ¹⁰B-enriched (¹⁰B glass) and ¹¹B-enriched (¹¹B glass) glasses. The glasses were irradiated with X-rays, He ions, or neutrons, and their thermoluminescence (TL) properties were investigated. The TL properties of the ¹⁰B and ¹¹B glasses after X-ray or He ion irradiation were similar. Meanwhile, the TL intensity of the ¹⁰B glasses was much larger than that of the ¹¹B glasses. The TL peaks of ¹⁰B glasses were observed in the irradiation range of 10⁹–10¹² n/cm², and the intensity increased monotonically with neutron fluence.
