| 内容記述 | Scintillation materials made from un-doped aromatic ring polymers can be potentially used for radiation detection. Here we demonstrate that Polysulfone (PSU) works without doped fluorescent guest molecules, and thus broadens the choices available for radiation detection. The transparent PSU substrate (1.24 g/cm3) significantly absorbs short-wavelength light below approximately 350 nm. Visible light absorption colours the substrate slightly yellow, and indigo blue fluorescence is emitted. The fluorescence maximum occurs at the intersection of the 340-nm excitation and 380-nm emission spectra; thus the emission is partially absorbed by the substrate. An effective refractive index of 1.70 is derived based on the wavelength dependence of the refractive indices and the emission spectrum. A peak caused by 976-keV internal-conversion electrons from a 207Bi radioactive source appears in the light yield distribution. The light yield is equivalent to that of poly (phenyl sulfone), which has a similar structure. Overall, un-doped PSU could be a component substrate in polymer blends and be used as an educational tool in radiation detection. | |||||
