· JVASP-154236· Dy2SnS5

Dy2SnS5 is a rare-earth tin sulfide ceramic compound combining dysprosium, tin, and sulfur in a ternary chalcogenide system. This is primarily a research material studied for its potential in thermoelectric and photovoltaic applications, where mixed-valence rare-earth compounds offer opportunities for tuning electronic and phononic properties. It belongs to a family of sulfide ceramics explored as alternatives to conventional semiconductors, though industrial adoption remains limited and the material is not yet commercialized at scale.
