摘要：
In this study, we successfully made Ag2O–Cs2O–MgO–Al2O3–P2O5 glasses with different Ag concentrations (0, 0.1, 0.3, 1.0, and 3.0 mol.%) by the melt-quenching method. We measured photoluminescence (PL) properties, the radio-photoluminescence (RPL) phenomenon, and spatial resolution on the X-ray imaging to check the capability of RPL imaging plate. RPL was observed in the Ag-doped samples by irradiating X-rays, and the new emission appeared at around 620 nm. According to the shape of the PL spectrum and lifetime, the emission was confirmed to be due to Ag2+ with lifetimes of 14.0–15.9 ns. In the X-ray imaging resolution test, the 3.0% Ag-doped sample had a spatial resolution of at least 10.0 LP/mm.
