Silver photochemical reactivity under electronic irradiation of zinc-phosphate and sodium gallo-phosphate glasses

Data set from Silver Photochemical reactivity under electronic irradiation of Zinc-Phosphate and Sodium Gallo-Phosphate glasses - Publication : Alassani F., Desmoulin J.-C., Cavani O., Petit Y., Cardinal T. and Ollier N. Silver photochemical reactivity under electronic irradiation of zinc-phosphate and sodium gallo-phosphate glasses. Journal of Non-Crystalline Solids 2023 vol.600, p.122009 (10 p.). HAL : Hal-03851869 Dataset production context : In the present work, the effect of electron irradiations on silver-containing phosphate glasses using a 2.5 MeV electron beam has been explored by Electron Spin Resonance (ESR) and luminescence spectroscopy. The process involved in the interaction of electron beam with both the silver-containing and silver-free phosphate glass matrix and the formation of colored centers is discussed. This allowed an understanding of the initial phenomena of electron deposition and charge trapping that supports the photosensitivity of these glasses by identifying the point defects and the Ag species. The effect of the silver concentration and the structure of the glass depending on the integrated dose have been investigated. The in-situ cathodoluminescence measurements give additional valuable information about the cascade of chemical reactions in the formation of new silver species, namely from the initial silver ions to the molecular silver clusters.

数据集制作背景：本研究采用2.5 MeV电子束，借助电子自旋共振（Electron Spin Resonance, ESR）与发光光谱技术，探究电子辐照对含银磷酸盐玻璃的影响。文中讨论了电子束与含银及无银磷酸盐玻璃基体的相互作用过程，以及色心的形成机制；通过识别点缺陷与银物种，阐明了支撑这类玻璃光敏性的电子沉积与电荷捕获初始现象。研究还考察了银浓度与玻璃结构对累积辐照剂量的依赖关系。原位阴极发光测量为新型银物种（从初始银离子到分子银团簇）形成过程中的化学反应级联提供了额外关键信息。更多详情可参阅原文。
