Title: Metal-loaded plastic scintillators for gamma-ray spectroscopy

Abstract

Exemplary embodiments of several new metal-loaded plastic scintillators are reported herein, comprising sterically and electronically isolated organotin additive complexes. Distance-dependent quenching relationships have been used as design criteria for the selection and synthesis of these organometallic additives, resulting in increased light yields and improved gamma-ray energy resolution values relative to previously reported PS/PVT examples. Fast scintillation decay properties have also been characterized in the prepared scintillators, rivaling the kinetics of stilbene-doped bibenzyl and BC-422Q-1% while providing higher light yields than these reference materials.
