摘要：

New single crystal of Ce-doped Tl2LiGdBr6 (TLGB) was investigated under x-ray and gamma-ray excitation. Two zone vertical Bridgman technique was used to grow this scintillation material. Under X-ray excitation, typical Ce3+ ion emission was observed between 397 and 456 nm peaking at 422 nm. An energy resolution of 17% (FWHM) and 17,400 +/- 1700 ph/MeV light yield was obtained for 662 keV gamma-rays excitation. Under gamma-rays excitation from a Cs-137 source, two decay time components of 29 ns (92%) and 197 ns (8%) were found at room temperature. Further investigation is underway for the optimization of the Ce-concentration in the host lattice. We expect improvement in the scintillation properties with a good quality crystal of this material.
