Claim Text:
1. A solid organic scintillator comprising a polymeric matrix in which are dispersed a first fluorophore compound and a second fluorophore compound and one or more metal methacrylics wherein the metal is selected from the group consisting of Pb and Sn, wherein said scintillator has a weight content of said chemical elements of at least 5% by weight relative to the total weight of the scintillator, and wherein the scintillator emits an emission spectrum comprising an emission peak at a wavelength of at least 550 nm and has a scintillation decay time of less than 20 ns, wherein the first fluorophore compound is according to formula (I): wherein: R 1 is a mesomeric donor group; R 2 is a hydrogen atom or mesomeric donor group the same or different from R 1 ; R 3 is: an acyl group; or a straight-chain or branched, saturated or unsaturated C a cyclic saturated C a saturated C an aryl or heteroaryl group, optionally substituted; or one of the salts thereof; and wherein the second fluorophore compound is a perylene-diimide compound according to formula (III): wherein R 4 , R 5 , R 6 , R 7 , R 8 and R 9 independently of each other represent a hydrogen atom, an optionally substituted straight-chain or branched, saturated or unsaturated C 1 to C 20 hydrocarbon group, or an optionally substituted aryl or heteroaryl group.
