Abstract
The possibility of using rare-earth 1,3-diketonate derivatives with the general formula [Ln(L1)4]M and [Ln(L1)3L2] as radioluminophores luminescing under the action of 3H β-particles was proved. Yellow-green (Tb) and red (Eu) phosphors were produced depending on the rare-earth element used. It was found that the studied compounds have an acceptable luminescence brightness for use in the manufacturing radioluminescent light elements.
