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% .
