Novel scintillating materials for neutron detection were fabricated by using the sol-gel method. The scintillating materials comprised borosilicate glass and poly(ethylene glycol) (PEG). The scintillation characteristics were examined under He irradiation, and it was found that the scintillation intensity increased with the concentration of PEG. It also increased linearly with the concentration of fluor 2-(4-tert-butylphenyl)-5-(4-biphenylyl)-1,3,4-oxadiazole (B-PBD). Furthermore, the scintillation intensity of the best sample was comparable to that of the commercially available plastic scintillator BC-454. It was shown that a fluor with larger solubility in the starting solution would further improve the scintillation property.
