Synthesis and characterization of low-melting scintillating glass doped with organic activator

New colliders for high-energy physics studies require scintillators with short decay time, high density, good radiation hardness and law cost. It is possible to make glass scintillators that can meet these requirements by doping organic scintillating activators into an inorganic glass host. In this research, p-terphenyl as the activator is doped into lead-tin-fluorophosphate glasses. There is no detectable change of the dopant on the densities and characteristic temperatures of the glass host. The hybrid scintillating glasses doped with p-TP possess 5 ns decay time and a broad fluorescence emission band, the peak of which is at about 545 nru. Although the light yields of the glasses are low, this research shows that it is possible to develop good hybrid scintillating glasses by doping organic activators into inorganic glass host.
