摘要：

The single crystals of CsSr1-yEuyCl3 and CsSr1-yEuyBr3 (0 <= y <= 0.05) grown by the Bridgman method have been investigated for their scintillation properties. The radioluminescence spectra of the crystals demonstrated a narrow band at 400-500 nm which peak position shifts continuously toward larger wavelength as the Eu2+ concentration increases. The scintillation light yield achieves maximal value of 33,400 +/- 1700 photons per MeV with energy resolution of 11.5% at CsSr0.95Eu0.05Cl3 and 31,300 +/- 1600 photons per MeV with energy resolution of 9% at CsSr0.95Eu0.05Br3. The decay times at room temperature are 2.7 +/- 0.2 mu s and 2.5 +/- 0.2 mu s, respectively. (C) 2013 Elsevier B.V. All rights reserved.
