We have synthesized Tb-doped oxyfluoride glasses by the conventional melt quenching method, and the potential for X-ray imaging applications was evaluated. The synthesized glass showed green emission under X-ray irradiation, which was suitable for the wavelength sensitivity of Si-photodiode. Although the lifetimes of Tb-doped glasses had a few milliseconds, Tb-doped oxyfluoride glasses were considered usable as integration-type detectors.
