Abstract
We developed a new $Rb_2LiCeCl_6$ scintillator and determined the scintillation and thermoluminescence properties of the scintillator. The emission spectrum of $Rb_2LiCeCl$ is located in the range of 350 ~ 410 nm, peaking at 368 nm and 378 nm, due to the 4f ${\rightarrow}$ 5d transition of $Ce^{3+}$ ions. The fluorescence decay time of the crystal is composed two components. The fast component is 71 ns (85%) and the slow component is 405 ns (15%) of the crystal. The after-glow is caused by the electron and hole traps in the crystal lattice. We determined physical parameters of the traps in the crystal. The determined activation energy(E), kinetic order(m) and frequency factor(s) of the trap are 0.75 eV, 1.48 and $3.0{\times}10^8s^{-1}$, respectively.
