Abstract
A class of polycyclic aromatic compounds containing at least two fused rings, is used to produce very bright liquid or plastic scintillators. When a member of this class, such as pyrene, is added at high concentration to a liquid or polymeric organic solvent, scintillation light output may be increased by between 40 and 100% as compared to existing commercial scintillating compositions. These new bright scintillator compositions can be used in scintillating optical fibers and plates made therefrom. These new scintillating optical fiber plates are particularly useful for diagnostic medical X-ray detection, and superior spatial resolution particle detection and measurement of high energy particles and radiation.
