Set of Pr3+-doped KLuS2 samples with different Pr concentration was synthesized in the form of transparent crystalline hexagonal platelets by chemical reaction under the flow of hydrogen sulfide. Their structural, optical and scintillation properties were investigated thoroughly by means of X-ray powder diffraction, time-resolved luminescence spectroscopy, scintillation light yield and decay measurements to assess the spectroscopic properties of Pr3+ ions in the KLuS2 host. The number of photons emitted in the first nanosecond of the scintillation response is evaluated and found considerably higher (1.6× – 2.5×) than that in commercial LYSO:Ce,Ca scintillator which shows the potential of Pr-doped KLuS2 for fast timing scintillator applications.
