New promising scintillators for gamma-ray spectroscopy: Cs(Ba,Sr)(Br,I)3
New scintillators belonging to Cs(Ba,Sr)(Br,I) 3 crystal family have been grown and investigated at RMD. The crystals were grown using the melt-based vertical Bridgman method. The iodide compositions were brighter compared to the bromides. Scintillation properties of these crystals have been studied...

| description | New scintillators belonging to Cs(Ba,Sr)(Br,I) 3 crystal family have been grown and investigated at RMD. The crystals were grown using the melt-based vertical Bridgman method. The iodide compositions were brighter compared to the bromides. Scintillation properties of these crystals have been studied under gamma irradiation, particularly CsBaI 3 :Eu in more details. CsBaI 3 :Eu has a tetragonal structure, and a density of 4.8 g/cc. The primary investigations of CsBaI 3 :Eu show an excellent energy resolution of 3.8% at 662 keV, high light yield of ~55,000 photons/MeV, and a primary decay time of 760 ns. For CsBaI 3 :Eu, the emission occurs over a single band (400-500 nm), which is due to d → f transition of Eu 2+ , with the emission wavelength peaking at 429 nm. The crystal shows high proportionality over a wide range of energies from 14 keV to up to 1.2 MeV. |
