Description
The scintillation properties of RbGd2Br7 crystals (ρ∼4.7 g/cm3) doped with Ce3+ concentrations of 1 and 5 mol% studied under X-ray and γ-quanta excitation are presented and compared with the properties of NaI(Tl) and other scintillators. For a sample doped with 5 mol% Ce, a light yield of about 55 000 photons/MeV with a main decay time of 60 ns was measured. With a photomultiplier tube, an energy resolution of 3.8% (FWHM) for the 662 keV full absorption peak has been observed. (orig.)
