Abstract: The morphological, structural, and luminescent properties of MGd_0.7Eu_0.3F₄ (M = Na, K) and RbGd_2.1Eu_0.9F₁₀ nanoparticles were systematically compared to elucidate the influence of alkali metal substitution on their behaviors. Additionally, the cytotoxicity of the potassium and rubidium compounds was evaluated for HEK-293 and HeLa cell lines.

Keywords: nanoparticles, rare-earth fluorides, luminescent nanomaterials, alkali metals, cytotoxicity.
