Neutron-induced thermoluminescence properties of Tb3+-doped CaO–Al2O3–B2O3 glasses

We fabricated neutron detection glasses, Tb3+-doped CaO­Al2O3­B2O3 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, ¡) reaction had good linearity in the irradiation range of 109 ­1013 neutrons/cm2
