Abstract

Ag-doped phosphate glasses have widely been used as radiophotoluminescence (RPL) dosimeters. However, the RPL center formation process is not fully understood. In this study, we investigated the RPL center formation process in Ag-doped Na-Al phosphate glasses. We observed that two RPL centers (Ag0 and Ag2+) were formed at temperatures higher than 100 and 250 K, respectively. In addition, activation energies of their formation were estimated to be 20 and 267meV, respectively. These results suggest that the electron transfer process is not a simple thermally activated process.
