Title: Efficient plastic scintillators utilizing phosphorescent dopants

Abstract

The authors demonstrate improved light yield from plastic scintillators utilizing a phosphorescent dopant to collect both singlet and triplet excitations created by ionizing radiation. They specifically considered poly(vinyltoluene) and poly(9-vinylcarbazole) doped with an Ir phosphor. They present the spectral, temporal, and integrated yield responses as a function of dopant concentration to pulses of 10 keV electrons. Both doped plastics yield a maximum light output of {approx}200% of anthracene with decay times <850 ns. High light yield was obtained for Ir element fractions up to {approx}10 wt %, implying that these scintillators may be useful for gamma detection.
