Abstract
With the rapid development of advanced nuclear systems,neutron-based medical therapies,and nuclear security technologies,the demand for neutron dosimetry materials with higher sensitivity,long-term stability,and engineering feasibility has grown substantially.Glass-based neutron dosimeters have attracted considerable interest due to their high compositional tunability,excellent chemical durability,strong radiation resistance,and capability for fabrication into bulk plates,thin films,and optical fibers.This review summarizes the interaction mechanisms between neutrons and matter,followed by an overview of four representative detection approaches,including fission,nuclear recoil,activation,and nuclear-reaction-based detection.The recent progress of various glass systems,including borosilicate,lithium silicate,phosphate glasses,and rare-earth-doped glasses,is comprehensively discussed,covering network structures,defect-center formation mechanisms,neutron-induced luminescence pathways,and dosimetric performance.Special attention is given to the 10B and 6Li,the role of Ce3+/Tb3+dopants in scintillation processes,and the correlation between glass network topology,radiation stability,and sensitivity.Based on these research developments,the potential of glass-based neutron dosimetry materials in high-resolution detection,fiber-based sensing,and wide-energy-range applications is further highlighted.This review aims to provide guidance for the structural design and engineering development of next-generation neutron dosimetry materials.关键词
