| 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. |
