To meet the present-day rate and radiation dose requirements, one would like to have a scintillator with the high radiation resistance of pure silica glass and the short fluorescence decay time of organic fluors. The new technology of sol-gel glass production permits the preparation of organic/ inorganic composite materials by doping the silica gels with organic fluors. The procedure of production of monolithic organiclinorganic composite materials, such as 2-(4-tert-butylphenyl)-5-(4-biphenylyl)-1,3,4-oxadiazole/Si02, p-terphenyll S O 2 , p-quaterphenyl/Si02, and 3-hydroxyflavone/Si02, and the associated characterization techniques are described. The efficiency of light production, the light attenuation, the time width of light pulse, and the radiation resistance of the scintillating sol-gel glass are discussed. Preliminary results indicate that this technical advance will permit the creation of new materials with potential application such as particle detectors which are both radiation hard and fast.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
