Growth and luminescent properties of Cs2HfCl6 scintillators doped with alkaline earth metals
Original language description
Nondoped Cs2HfCl6 (CHC) and alkaline earth metal-doped CHC (AE:CHC) crystals were grown by the vertical Bridgman–Stockbarger method. The spectra of the AE:CHC under X-ray excitation were similar to those for the AE-free crystal. Thus, AE doping did not change emission wavelength of CHC. We determined the light outputs and energy resolutions of nondoped CHC and AE:CHC by measuring pulse-height spectra under 662-keV gamma-ray excitation of a 137Cs source. Nondoped CHC had a light output of 44000 photons/MeV and energy resolution of 5.2%, the 0.5 at% Sr:CHC had a light output of only 28000 photons/MeV and energy resolution of 10%. Scintillation decay also did not change. The nonproportional response values of light output versus gamma-ray energy did not improve in AE:CHC either. The doped AEs can be responsible for creation of defect trap levels which would hamper the carrier transport in CHC structure.
