This project aims to use the surface plasmon resonance (SPR) technology in study on the dielectric properties change at the interface between gold and 10B nano-fluid layer under neutron irradiation, exploring the novel neutron detection technology. 10B composite magnetic nano materials will be chemically fabricated and the response of the fabricated nanomaterials to neutron will be observed. The emphasis will be laid on the response of the dielectric properties of the nano-layer at the gold surface to thermal neutron by combination of SPR with the finite element method in coupling of radiation field and fluid field, involving the change in the dielectric properties due to the concentration distribution and transfer of the medium at the interface. Based on the response of 10B nanomaterials, we will develop a novel, high sensitive neutron detection method and detector, and the neutron imaging.
