For many years, the radiophotoluminescence (RPL) of Ag-doped phosphate glass has beenexploited in personal dosimetry. In this study, we investigated the optical properties of Ag-dopedphosphate glasses of various compositions containing alkali metals as cations. We found that thepeak wavelengths of the RPL bands depend on alkali metal species. Corresponding excitationbands also appeared in the excitation spectra after irradiation. In addition, we observed differencesin the stability of the RPL fluorescent centers after heat treatment. These results indicate that RPLfluorescent center formation and initialization processes depend on the alkali metal species in thehost phosphate glasses.
