Commercial silver-doped phosphate glass is a promising material for a solid-state radio-photoluminescent (RPL) dosimeter. It has several promising characteristics, such as RPL intensity linearity with the ionizing irradiation dose, data accumulation, no fading, and measurement repeatability. It can be used as personal, environmental, and clinical dosimeter as well. The objective of this study was to synthesize silver-doped phosphate glass in the laboratory and compare its RPL properties with those of a commercial GD-352M glass. The emission and the excitation properties of the synthesized and commercial glasses were measured before and after X-ray irradiation. An intense orange emission peak at 600 nm and an excitation peak at 320 nm were measured for the synthesized glass after X-ray irradiation. The radiative lifetime of the synthesized glass had two decay components for the orange Radio-Photoluminescence.
