Abstract

In this paper, the crystal growth and scintillation properties of a $Cs_2NaCeBr_6$ crystal are presented. The crystal was grown with the Bridgman method by using a two-zone transparent furnace. The investigation of the scintillation properties of the crystal were performed under excitation by X-rays, $\gamma$-rays and protons at room temperature. When the $Cs_2NaCeBr_6$ crystal was excited by X-rays and protons, the emission spectrum of the crystal was observed in the range of 380 $\sim$ 460 nm, which is due to the 5d $\rightarrow$ 4f transitions of $Ce^{3+}$. The decay times of the $Ce^{3+}$ emission excited by $^{137}Cs$ 662 keV $\gamma$-rays. were about 140 ns (94 %) and 880 ns (6 %). The energy resolution of the crystal was obtained to be 6.7 % for the $^{137}Cs$ 662 keV $\gamma$-rays and the absolute light yield of the $Cs_2NaCeBr_6$ crystal was about 25,000 phs/MeV.
