Optical and scintillation properties of CeCl3 and Ce doped LaBr3 single crystals grown by modified micro-pulling-down method

We developed a modified micro-pulling-down (μ-PD) method for crystal growth of halide materials with hygroscopic nature. By the modified μ-PD method, CeCl 3 and Ce doped LaBr 3 [Ce: LaBr 3 ] single crystals were grown and the crystals indicated high transparency. In the photoluminescence measurement...

Description
Summary:We developed a modified micro-pulling-down (μ-PD) method for crystal growth of halide materials with hygroscopic nature. By the modified μ-PD method, CeCl 3 and Ce doped LaBr 3 [Ce: LaBr 3 ] single crystals were grown and the crystals indicated high transparency. In the photoluminescence measurements, emissions of Ce 3+ ion 5d-4f transition were observed in the both crystals of CeCl 3 and Ce: LaBr 3 . Emission peak originated from 5d-4f transition of Ce 3+ ion were observed around 430 nm by radiation from X-ray. In the decay curve of Ce:LaBr 3 single crystal with radiation of γ-ray from 137 Cs source, decay time was about 36 ns.
