Abstract

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