BISMUTH-CHARGED STRUCTURED SOLID ORGANIC SCINTILLATOR

摘要

The invention relates to a scintillator for imaging using X-rays or gamma rays or charged particles, including a network of glass capillaries (1) with an inner diameter no greater than 500 micrometres, said capillaries being filled with a polymer material (2) made up of at least: (i) a monomer selected from the group comprising vinyltoluene, styrene and vinylxylene and the isomers thereof; (ii) a cross-linking agent made up of a divinylbenzene or a dimethacrylate having a central chain which includes 1 to 12 carbon atoms; and (iii) triphenylbismuth, the cross-linking agent being provided to make up 10 wt % to 60 % wt of the mixture thereof with the monomer, and the triphenylbismuth being provided to make up at least 5 wt %, the cross-linking agent being provided in a ratio of 0.75 to 2.25 times the weight content of the triphenylbismuth.
