Abstract

We developed a modified micro-pulling-down (-PD) method for crystal growth of halide materials with hygroscopic nature. By the modified -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: LaBr 3. 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 γ-ray from 137Cs source, decay time was about 36 ns
