Abstract :
We grew a Gd-doped lead chloride single crystal by the Bridgman method and investigated scintillation properties of the crystals at low temperature. We measured the relative light yield, energy resolution, fluorescence decay time, and proportionality of the crystals for the gamma-ray at low temperature. The energy resolution is measured to be 25.6% for the137Cs 662 keV gamma-ray, and the fluorescence decay time of the crystal is composed of two components with decay times of 1.35 and 6.20 mus at 173 K.
