摘要：

This paper presents study of the gamma-rays induced radiation damage in the LaBr3:Ce crystal. The light output and transmittance are measured before and after gamma-rays irradiations with an integrated dose up to 10(6) rad for two LaBr3:Ce samples. After gamma-rays irradiation, LaBr3:Ce crystal shows very slow recovery process or has no recover under room temperature, indicating that the radiation damage in LaBr3:Ce crystal is not dose date dependent. Meanwhile, it's found that the radiation induced color centers are respectively peaked at the wavelength of 448 nm, 512 nm and 590 nm. Those color centers should be ascribed to the V-k, V-F and F center respectively. (C) 2014 Elsevier Ltd. All rights reserved.
