Abstract
Polymerization composition for manufacturing a hybrid material for plastic scintillation detection comprising: a) monomers, oligomers or their mixtures intended to form at least one constituent polymer of a polymeric matrix and b) a liquid fluorescent mixture comprising i) 95.6 molar % to 99.1 molar % of a main primary fluorophore consisting of naphthalene and ii) 0.9 molar % to 4.4 molar % of an additional primary fluorophore; wherein the centroid of the light absorption spectrum and of the fluorescence emission spectrum, the fluorescence decay constant and the fluorescence quantum yield of which are judiciously chosen. The decay constant of the fluorescence of the hybrid material manufactured with the polymerization composition is intermediate between that of a fast plastic scintillator material and of a slow plastic scintillator. Further, it can be chosen over a wide range. The invention also relates to ready-for-use kits for manufacturing a polymerization composition.
