Immobilization of Eu3+ Ions in Zeolite Matrices in Order to Develop Solid-State Radioluminescent Light Sources

Resumo

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⁺.
