摘要：

The mechanism behind radiophotoluminescence (RPL) emission in Ag-doped alkali -phosphate glass remains unclear. To contribute to resolving this issue, the authors measured and analyzed the temporal change of electron spin/paramagnetic resonance (ESR) spectrum of a recently developed, weather -resistant RPL glass, named "SAPANS," after irradiation with X-rays. As a result, a continuous gradual increase in Ag 2 + -derived signals was observed even at four weeks post -irradiation, which corresponded well with the time build-up pattern of the RPL of SAPANS. In contrast, the signals derived from phosphorous -oxygen -hole centers (POHC) rapidly decreased over a few days. The peaks of Ag 0 and Ag 2 + were not successfully separated from the ESR spectra because of the possible overlap of unidentified peaks, which implies a complex mechanism of RPL-center formation in Ag-doped alkali -phosphate glass that requires further investigation.
