Abstract

Matériau hybride pour la mesure par scintillation plastique comprenant : - une matrice polymérique ; et, - un mélange fluorescent incorporé dans la matrice polymérique et comprenant par rapport au nombre total de moles de fluorophore primaire dans le mélange fluorescent incorporé i) 80 % à 99,6 % molaire d'un fluorophore primaire principal constitué de naphtalène et ii) 0,4 % à 20 % molaire d'un fluorophore primaire supplémentaire dont le centroïde du spectre d'absorption lumineuse et du spectre d'émission de fluorescence ont respectivement une longueur d'onde comprise entre 250 nm et 340 nm et comprise entre 330 nm et 380 nm, la constante de décroissance de fluorescence est comprise entre 1 ns et 10 ns, et le rendement quantique de fluorescence dans un solvant apolaire est compris entre 0,2 et 1. La constante de décroissance de la fluorescence du matériau hybride est intermédiaire entre celle d'un matériau scintillateur plastique rapide et d'un matériau scintillateur plastique lent. En outre, elle peut être choisie dans une large gamme. L'invention concerne également le procédé de fabrication du matériau hybride.
