We fabricated 10B-enriched (10B ceramics) and 11B-enriched (11B ceramics) Ca2B2O5:Tb ceramics as thermoluminescence (TL) materials for neutron detection applications. The TL properties of the ceramics after X-ray irradiation, particle beam irradiation, and neutron irradiation were investigated. The TL properties of the 10B ceramics and 11B ceramics after X-ray irradiation were similar, whereas the neutron-induced TL intensity of the 10B ceramics was significantly higher than that of the 11B ceramics. The different TL properties of these ceramics are due to the α-rays, Li ions, and γ-rays generated during the 10B(n, α)7Li reaction. The lower limit of neutron detection by the ceramics was less than 2 107 neutrons cm-2, which was lower than those of several previously reported TL materials. Therefore, these ceramics can be applied as TL dosimetry materials for neutron detection.
