    • A series of Eu2+ doped Cs1-xRbxCaBr3 solid solutions were grown using the Bridgman-Stockbarger technique. Their photoluminescence and scintillation properties are studied. Upon optical and X-ray excitation, the Cs1-xRbxCaBr3 and Eu2+ activated samples show a band, which can be attributed to the 5d-4f transition in Eu2+. The decay time constants become shorter with increasing Rb content and lie in the range of 3-4 mu s. The scintillation performance of solid solutions Cs1-xRbxCa0. 95Eu0.05Br3 is improved compared with the end members (CsCa0.95Eu0.05Br3 and RbCa0.95Eu0.05Br3). The best energy resolution of 6.4% at 662 keV was determined for Cs0.2Rb0.8Ca0.95Eu0.05Br3 , and the best light yield, equal to 61.2% of Nal:TI, was demonstrated by Cs0.4Rb0.6Ca0.95Eu0.05Br3.

  • Effects of europium concentration on luminescent and scintillation performance of Cs0.2Rb0.8Ca1-xEuxBr3 (0 <= x <= 0.08) crystals
  • 2022
  • Ingår i: Journal of Rare Earths. - : Elsevier. - 1002-0721 .- 2509-4963. ; 40:1, s. 29-33
  • Tidskriftsartikel (refereegranskat)abstract
    • A series of Cs0.2Rb0.8Ca1-xEuxBr3 (0 <= x <= 0.08) crystals doped with different concentrations of Eu2+ were grown using the Bridgman-Stockbarger method. The work describes the influence of Eu2+ concentration on the luminescent and kinetic properties of Cs0.2Rb0.8Ca1-xEuxBr3 crystals, as well as on their scintillation performance. The maximum in the radioluminescence spectra of these crystals shifts from 439 to 446 nm with increasing europium concentration. The scintillation decay times of Cs0.2Rb0.8Ca1-xEuxBr3 lengthen with the Eu2+ content. The best light output of 33600 photons/MeV is obtained for Cs0.2Rb0.8Ca0.93Eu0.07Br3, and the best energy resolution of 6.9% is found for Cs0.2Rb0.8Ca0.94Eu0.06Br3.
