Abstract

Micelle-SiO₂ hybrid gels were designed and prepared as solid-state neutron-detecting materials based on micelle self-assembly. An organic liquid scintillator was homogeneously co-doped in a neutron absorbing lithiated PEG-silica gel through a micelle system. For this purpose, nonionic and anionic surfactants were used to solubilize the organic scintillator. This blue light emitting (λ_em=413 at 340 nm excitation) neutron-detecting material with only a 0.1 wt% of a ⁶Li⁺-doping showed a great response toward a neutron radiation as demonstrated in comparative investigation by using pulse-height spectra.
