As a type of scintillator, scintillation glass has the advantages of low cost, high stability, controllable shape, and ability to be prepared on a large scale. In this paper, a traditional fusion quenching method was used to prepare a cerium-terbium co-doped glass. The green characteristic light of Tb ion was observed at 543 nm. Moreover, through the doping sensitization of Ce ions, the luminescence of Tb was successfully enhanced. The material has high X-ray response sensitivity, complete stability and strong X-ray emission intensity. We use a simple X-ray imaging platform for imaging, and the results show that our glass has a spatial resolution of 7.0 lp/mm.展开更多
