چکیده انگلیسی
TlSr2I5: Eu2+ is a newly discovered scintillator that show promising scintillation properties for X- and γ-ray spectroscopy applications. Two zone vertical Bridgman technique is used for the growth of this scintillator. Luminescence properties of the grown crystals are measured under X-ray excitation at room temperature. Pure and Eu2+ doped crystals contained broad emission bands between 445 and 670â¯nm peaking at 528â¯nm and 430-600â¯nm peaking at 463â¯nm, respectively. Energy resolution, light yield and decay time profiles are studied under 662â¯keV γ-ray excitation using 137Cs radioactive source. Energy resolution of 4.2% (FWHM) is obtained for 3â¯mol% Eu2+ doped crystal. For the same sample, light yield of 70,000â¯ph/MeV is also obtained. Three and two decay constants are observed for the pure and Eu2+ doped samples, respectively at room temperature. Effective Z-number and density are found to be 61 and 5.30â¯g/cm3, respectively.
