Abstract
The scintillation properties of
(pure, 0.5%, 2%, and 5%
), a new member of the generation of
doped lanthanide trihalide scintillators, are presented. This material has a calculated density of 5.6
and an atomic number
of 60.2. Under optical and X-ray excitation,
emission is observed to peak at 472 and 535 nm. A high light yield of 76 000 photons per MeV (ph/MeV) was measured for
:2%
.
has a nonexponential decay time. The contribution of short decay components (within 50 ns) to the total light yield is around 50%. An energy resolution (full-width half maximum over peak position) for the 662 keV full energy peak of
was observed for
:0.5%
