Abstract
Polyvinyltoluene-based nanocomposite plastic scintillators containing uniformly dispersed ytterbium fluoride nanoparticles are prepared by in-situ thermal polymerization. The deep-blue-emission nanocomposite monoliths are capable of producing a full energy phtotpeak when exposed to Cs-137 (662 keV) gamma radiations. The effects of monolith dimension and nanoparticles content on scintillation light yield and energy resolution are studied. A light yield of 65% (compared with the commercial standard Eljen-212) and a photopeak energy resolution of 9.2% was obtained using a sample loaded with 24.5 wt% ytterbium fluoride nanoparticles.
