Scintillation Performance of Aliovalently-Doped ${\rm CeBr}_{3}$

Recent R&D Trends in Inorganic Single‐Crystal Scintillator Materials for Radiation Detection

“…Afterglow profi les of CsI:Tl + ,Yb 2+ group B crystals after X-ray pulse excitation. [ 68 ] Only Pb 2+ appeared to be detrimental to the scintillation properties of CeBr 3 , and all the doped crystals showed a noticeable increase in the fracture toughness compared to undoped CeBr 3 .

Site-Directed Research and Development FY 2012 Annual Report

“…Since then, numerous derivatives of this family have been explored, including undoped, self-activated cerium tribromide (CeBr 3 ) (Shah 2005). Although the scintillation performance of these cerium-doped and ceriumbased crystals is outstanding, their mechanical properties are not generally conducive to growth of large single crystals (Harrison 2008(Harrison , 2009(Harrison , 2010.…”

Crystal growth, optical properties, and scintillation responses of Pr-doped CeBr3 single crystals

“…6,[13][14][15][16][17][18][19] In these halide scintillators, a CeBr 3 single crystal with a hexagonal crystal structure (space group: P6 3 =m) shows a relatively high light yield (>60,000 photons=MeV) and a short decay time (∼19 ns) under γ-ray irradiation in addition to an excellent energy resolution (<4%). [20][21][22][23][24][25][26][27] The CeBr 3 single crystal is one of the most appropriate candidates as a scintillator for positron annihilation lifetime spectroscopy (PALS) 27) and time-of-flight positron emission tomography (TOF-PET) 28) owing to the high spatial and timing resolutions. The nonproportionality of the CeBr 3 single crystal under γ-ray irradiation was improved by divalent cation doping in a previous study.…”
