Synthesized recombination-type zinc sulfide phosphors used in solid-state radioluminescent light sources (SSRLS) are the object of the research. In the course of the study, experimental data were obtained for the first time on the effect of the amount of the incorporated activator on the brightness-spectral characteristics of radioluminescence upon excitation by β-radiation of tritium. Data were obtained on the changes in the radioluminescence parameters under various synthesis conditions, phase composition and electron-beam modification of the crystal structure of the initial phosphors. The results of the work make it possible to find the best light compositions for the use in solid-state radioluminescent light sources
