Abstract

The influence of scavengers of the primary water radiolysis products \({\text{e}}_{{{\text{aq}}}}^{ - }\) and the H atom on the spectra and intensity of radioluminescence and photoluminescence of the Tb³⁺ ion in aqueous solutions of TbCl₃ and Tb(NO₃)₃ is considered. The effect of activation of Tb³⁺ radioluminescence in the presence of H scavengers has been revealed, indicating the presence of a specific (Tb³⁺)* quenching reaction by this radiolysis product, which is inhibited by its scavengers. Enhancement in the activation has been revealed in the joint presence of H and \({\text{e}}_{{{\text{aq}}}}^{ - }\) scavengers in the solution, with a similar effect of activation of Tb³⁺ radioluminescence being previously established for \({\text{e}}_{{{\text{aq}}}}^{ - }\) scavengers.

论氢原子对水溶液中 Tb3+ 离子辐射的特异性淬灭

摘要研究了原生水放射分解产物 \({\text{e}}_{{text\{aq}}}}^{ - }\) 和 H 原子的清除剂对 TbCl3 和 Tb(NO3)3 水溶液中 Tb3+ 离子的放射发光和光致发光的光谱和强度的影响。研究揭示了在 H 清除剂存在的情况下 Tb3+ 放射性发光的活化效应，表明这种放射性分解产物存在特定的 (Tb3+)* 淬灭反应，而清除剂会抑制这种反应。在溶液中同时存在 H 和 \({\text{e}}_{{text\{aq}}}}^{ - }\) 清除剂的情况下，活化效果得到了增强，而 \({\text{e}}_{{text\{aq}}}}^{ - }\) 清除剂也具有类似的活化 Tb3+ 放射性发光的效果。

期刊介绍： High Energy Chemistry publishes original articles, reviews, and short communications on molecular and supramolecular photochemistry, photobiology, radiation chemistry, plasma chemistry, chemistry of nanosized systems, chemistry of new atoms, processes and materials for optical information systems and other areas of high energy chemistry. It publishes theoretical and experimental studies in all areas of high energy chemistry, such as the interaction of high-energy particles with matter, the nature and reactivity of short-lived species induced by the action of particle and electromagnetic radiation or hot atoms on substances in their gaseous and condensed states, and chemical processes initiated in organic and inorganic systems by high-energy radiation.
