From scintillator to phosphor: X-ray induced long afterglow red luminescence from Bi4Ge3O12:Eu3+
Zewen Liu,Tongyan Lin,Naihui Chen,Weichao Meng,Pengbo Cai,Runyao Liu,Xiaoyan Fu,Hongwu Zhang +7 more
TL;DR: Wang et al. as discussed by the authors designed a novel strategy to develop efficient X-ray-induced long afterglow luminescent materials from scintillator to phosphor, which showed that Bi4Ge3O12: Eu3+ can produce excellent x-ray induced red long-afterglow luminance which appeared at 589, 612, 655 and 705 nm corresponding to the 5D0→7Fj(j = 1,2,3,4) transitions, respectively.
