Abstract

Advanced refining techniques have enabled the application of high-purity aromatic ring polymers with favourable scintillation characteristics for radiation detection, without requiring doped fluorescent guest molecules. Here, we show the optical characteristics of pure poly (vinyltoluene) (PVT). It has a 285-nm excitation maximum and a 315-nm emission maximum. The effective refractive index is 1.66, which was derived from its emission spectrum. Light yields were determined by irradiation with ¹³⁷Cs and ²⁰⁷Bi radioactive sources. The light attenuation length is an unexpectedly high 40.5±0.3 mm. These results indicate that thick samples of undoped PVT can be used as effective scintillation materials, and will stimulate future applications.
