· JVASP-113126· Tb2MgS4

Tb2MgS4 is a rare-earth magnesium sulfide ceramic compound combining terbium, magnesium, and sulfur elements. This material is primarily of research and developmental interest rather than established in high-volume industrial production, belonging to the rare-earth chalcogenide family that shows promise for optoelectronic and photonic applications due to rare-earth luminescent properties.
