Lu2 S4
semiconductor· Lu2 S4
Lu₂S₄ is a rare-earth sulfide semiconductor compound combining lutetium with sulfur in a 2:4 stoichiometric ratio. This material belongs to the rare-earth chalcogenide family and is primarily of research and developmental interest rather than established in high-volume industrial production. Lu₂S₄ is explored for optoelectronic and photonic applications where its wide bandgap and luminescent properties could enable ultraviolet or visible-range devices, though commercial adoption remains limited compared to more conventional semiconductors.
