Highly resolved and refreshable X-ray imaging from Tb3+ doped aluminosilicate oxyfluoride glass scintillators
JOURNAL OF MATERIALS CHEMISTRY C(2023)
摘要
Radiation detection is of current interest for diverse applications, such as biomedical diagnostics, computerised tomography scanning and safety detection. High-quality radiation imaging for targeted objects with irregular shapes requires use of scintillators with high resolution, large scale and moderate radiation tolerance. Here, a series of Tb3+ doped aluminosilicate oxyfluoride glass samples are designed. Strong photoluminescence excited by ultra-violet light and radioluminescence excited by X-ray were obtained. The optimal specimen presents a highly integrated X-ray excited luminescent intensity (163% of that of a commercial Bi4Ge3O12 scintillator). The specimen also exhibits highly resolved X-ray imaging with an extraordinary spatial resolution (20 lp mm(-1)), which surpasses that of many halide scintillators, and might be a record resolution for a glass scintillator. The soft glass network furnishes the possibility for refreshable X-ray imaging. Those results provide a valid platform for glass scintillators for the practical utilisation in large areas and high-resolution imaging.
