摘要

Tb-doped LiYSiO4 was fabricated and evaluated as thermoluminescent (TL) materials for thermal neutron detection. Tb was introduced as a luminescent center. Because neutron fields generally contain gamma-rays, a subtraction method was employed to enable neutron–gamma discrimination, utilizing the difference in TL responses between nLi (natural isotopic abundance) and 6Li-enriched samples, due to the high neutron capture sensitivity of 6Li. After X-ray irradiation, both samples exhibited similar TL glow curves, which indicate their comparable X-ray and gamma-ray responses. After neutron irradiation, the 6Li-enriched sample showed significantly higher TL intensity than the nLi sample, and the observed difference was attributed to neutron-induced TL signals. Thermal neutron fluence was measurable within the investigated range of 105–109 neutrons cm−2 with an estimated detection limit of 6.2 × 104 neutrons cm–2, which is comparable to that of commercial neutron dosimeter pairs such as TLD-600/TLD-700.
