The optical properties of phosphate glass (PG) with two different impurities, namely, aluminum and tin, were investigated. Broad white luminescence was observed from PGs with tin and aluminum impurities under deep ultraviolet exposure. Through emission and excitation spectroscopy and decay curve measurement, it is assumed that the origin of the broadband luminescence differs depending on the impurities introduced. In addition, time-resolved emission spectral analysis revealed the difference in decay constant at each wavelength. The results obtained in this study might give important information about two potential impurities of PG for a better understanding of background noise and the functions of widely used radio-photoluminescence (RPL) dosimeters.
