Abstract

Energy transfer within plastic scintillator was investigated by incorporating nanocomposite Quantum Dot as the mediator and catalyst. Scintillation efficiency was enhanced through Polyvinyl Toluene (PVT) scintillating polymer with near-UV emission Cadmium Sulfide Quantum Dot under minute loading. Energy resolution was enhanced in beta and gamma spectroscopy compared to non-doped PVT samples. Sharp emission was observed possibly intrinsic to the polymer attributing to the degree of energy transfer from the nanocomposite. These results indicates improvements in scintillating system where Quantum Dots helps facilitate energy transfer in detecting ionizing radiation.
