摘要：

Powder sample of Cubic phase BaF2:Ce phosphor was synthesized by chemical co-precipitation method and annealed at 500 degrees C for 2 h. The synthesized powder of BaF2:Ce phosphor was characterized by XRD, which shows FCC structure with 30 nm crystallite size. TEM images show a cubic structure and FTIR contains the existence of F-Ba-F, C-H, C=C, and O-H bonds. Glow curve of the Thermoluminescence contains two major peaks, one at 175 degrees C and another at 275 degrees C. The intensity of the major dosimetric peak (175 degrees C) observed to be increased linearly from 1 Gy to 3 kGy for the doses of( 60)Co gamma rays and then saturates. Overall, the new BaF2:Ce phosphor shows good material properties for the high gamma dose measurement applications.
