| Abstract | Halide single crystals with relatively small band-gap show favorable scintillation properties. We grew undoped and Pr doped CeBr3 crystals by a modified micro-pulling-down (μ-PD) method. Crystals of approximately 10 mm in length and 3mm in diameter were obtained. Fast scintillation decay components observed both for the undoped and Pr doped crystals were characterized by a decay time of approximately 16 ns. From the emission spectra excited by 260 nm light, emission peaks originating from Pr 4f-4f transitions were observed at 490, 620 and 650 nm in the Pr–doped sample. In excitation spectra for the 400 nm emission wavelength, the excitation peak observed around 340 nm in the undoped sample was shifted to shorter wavelengths in the Pr-doped one. |
