· JVASP-10661· Lu2MgSe4

Lu2MgSe4 is a ternary ceramic compound combining lutetium, magnesium, and selenium, belonging to the family of rare-earth metal selenides. This is a research-phase material not yet widely deployed in production, studied primarily for its potential as an optical or electronic functional ceramic given the properties of its constituent elements. The lutetium-magnesium selenide system is of interest in materials science for exploring novel semiconducting, scintillation, or solid-state lighting applications where rare-earth compounds typically offer luminescent or electronic functionality.
