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.
