Growth and scintillation characterizations of the newly developed cerium doped Rb<SUB>2</SUB>LiGdBr<SUB>6</SUB> (RLGB) single crystals were investigated. RLGB, which belongs to bromo-elpasolite crystal family, was grown by the vertical Bridgman technique with nominally 1%, 5%, and 10% Ce<SUP>3+</SUP>-concentration (mole%). X-ray excited luminescence spectra show typical Ce<SUP>3+</SUP> bands between 350 to 460nm wavelength regions. A good energy resolution of 5.5% (FWHM) and light yield of 25,500+/-2600ph/MeV for 662keV γ-rays were observed at 5% Ce<SUP>3+</SUP>-concentration. Under γ-ray excitation, RLGB:Ce<SUP>3+</SUP> crystals display multi-exponential decays with Ce<SUP>3+</SUP> like decay components at 23ns and 29ns for 1% and 5% Ce-concentrations, respectively. From the results, it is expected that this scintillator could be used as a thermal neutron detector because of Li and Gd ions in the host lattice. Also, like other inorganic halide scintillators, it is very hygroscopic.
