Abstract

Immobilization of europium ions in the Rho, Beta, and paulingite zeolites using ion exchange is studied in order to search for the optimal alumosilicate matrix for the development of solid-state radioluminescent light sources. The phase composition, thermal stability, moisture adsorption ability, and spectral characteristics of the specimens are studied. It is determined that Beta zeolite possesses the highest sorption capacity, high chemical and thermal stability, a significant constant capacity by water, and the highest cation-exchange characteristics regarding Eu³⁺.

为了开发固态放射性发光光源，将Eu 3+离子固定在沸石基质中

摘要

研究了使用离子交换将euro离子固定在Rho，Beta和泡桐石沸石中的方法，目的是寻找开发固态放射性发光光源的最佳铝硅酸盐基质。研究了样品的相组成，热稳定性，吸湿能力和光谱特征。已经确定，β沸石具有最高的吸附容量，高的化学和热稳定性，显着的水恒定容量以及关于Eu ³⁺的最高的阳离子交换特性。
