Abstract

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.

用玻璃网络改性剂增强掺银磷酸盐玻璃的辐射光致发光

商用掺银磷酸盐玻璃因其优异的放射光致发光特性而广泛应用于个人和环境剂量学。本研究旨在通过在掺银磷酸盐玻璃中加入不同的玻璃网络改性剂（Na2O, NaCl, NaBr），并将其性能与商用GD450玻璃进行比较，以提高RPL灵敏度。根据x射线照射前后的光致发光特性和剂量响应评价了改性玻璃。在这些样品中，nabr改性玻璃显示出最高的灵敏度，表明在工业辐照监测、辐射硬度测试和高剂量环境剂量学方面具有潜力。

期刊介绍： The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid. We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
