We report an investigation on pure and doped PbFCl crystals. Optical and scintillation properties, such as emission and transmittance spectra, light output and decay kinetics, were measured at different temperatures. Three emission bands at 2.27, 2.85 and 3.39 eV are observed at 77 K. Thermal quenching effect is also observed. While a scintillation component peaked at 400 nm with 3 ns decay time is...
An effort has been made to introduce scintillation light in lead fluoride crystals by selective doping. It was found that some rare earth ions doped in the crystal may serve as luminescence centers. The photo- and X- luminescence spectrum, the decay time constant and the light output of these doped samples are presented. Because of the slow decay time these doped lead fluoride samples fall short to...
