Enhanced radiophotoluminescence in silver-doped phosphate glasses with glass network modifiers

초록

Commercial silver-doped phosphate glass is widely used in personal and environmental dosimetry due to its excellent radiophotoluminescence (RPL) characteristics. This study aims to enhance RPL sensitivity by incorporating different glass network modifiers (Na2O, NaCl, NaBr) into silver-doped phosphate glass and comparing their performance with that of commercial GD450 glass. The modified glasses were evaluated based on their photoluminescence characteristics and dose response before and after X-ray irradiation. Among the samples, NaBr-modified glass showed the highest sensitivity suggesting potential for industrial irradiation monitoring, radiation hardness testing, and high-dose environment dosimetry.
