Popis: The single crystals of CsSr 1− y Eu y Cl 3 and CsSr 1− y Eu y Br 3 (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 Eu 2+ concentration increases. The scintillation light yield achieves maximal value of 33,400 ± 1700 photons per MeV with energy resolution of 11.5% at CsSr 0.95 Eu 0.05 Cl 3 and 31,300 ± 1600 photons per MeV with energy resolution of 9% at CsSr 0.95 Eu 0.05 Br 3 . The decay times at room temperature are 2.7 ± 0.2 μs and 2.5 ± 0.2 μs, respectively.
