摘要：

We developed a modified micro-pulling-down (mu-PD) method for crystal growth of halide materials with hygroscopic nature. By the modified mu-PD method, CeCl3 and Ce doped LaBr3 [Ce: LaBr3] single crystals were grown and the crystals indicated high transparency. In the photoluminescence measurements, emissions of Ce3+ ion 5d-4f transition were observed in the both crystals of CeCl3 and Ce: LaBr3. Emission peak originated from 5d-4f transition of Ce3+ ion were observed around 430 nm by radiation from X-ray. In the decay curve of Ce:LaBr3 single crystal with radiation of gamma-ray from Cs-137 source, decay time was about 36 ns
