Abstract

The enhancement of gamma scintillation light yield in organic plastic scintillators is of great interest for radiation detection applications, particularly in national security, medical imaging, and high-energy physics. This study presents novel polymer matrices incorporating thermally activated delayed fluorescence (TADF) compounds and alternative fluorene-based materials. These materials exhibit significantly improved scintillation efficiency over conventional polyvinyl toluene (PVT) and polystyrene-based scintillators. Comprehensive photophysical characterization, including photoluminescence and radioluminescence measurements, was performed using photomultiplier tubes (PMTs) and silicon photomultipliers (SiPMs). The results suggest that TADF-enhanced scintillators achieve superior energy harvesting capabilities, offering a promising route for the development of next-generation organic scintillators.
