摘要

Sb3+-doped Cs2HfCl6 scintillation crystals were synthesized using a solution process, which does not require a high synthesis temperature, hence reduces the synthesis cost significantly. Doping Sb3+ into Cs2HfCl6 induced luminescence approximately 640 nm in wavelength. The scintillation decay of the Sb3+-doped Cs2HfCl6 became faster than those of undoped one. The scintillation light yield of the sample doped with 0.5 at. % Sb3+ was 12,400 ph/MeV.
