  In this study we present our preliminary report on the scintillation
properties of new Ce-doped Tl2LaBr5 single crystal. Two zones vertical Bridgman
technique is used for the growth of this compound. Pure and Ce-doped samples
showed maximum emission peaks at 435 nm and 415 nm, respectively. Best light
yield of 43,000+-4300 ph/MeV with 6.3% (FWHM) energy resolution is obtained for
5% Ce-doped sample under {\gamma}-ray excitation. Single exponential decay time
constant of 25 ns is observed for 5% Ce doped sample. Effective Z-number is
found to be 67, therefore efficient detection of X- and {\gamma}-ray will be
possible. Preliminary results revealed that this compound will be an ideal
candidate for the medical imaging techniques. Further investigations are under
way for the determination of optimized conditions of this compound.
