KCeS2

KCeS2 is an experimental rare-earth sulfide ceramic compound containing potassium and cerium, belonging to the class of mixed-metal chalcogenides. This material remains largely in the research phase, studied for its potential in optoelectronic and functional ceramic applications where rare-earth compounds are leveraged for their unique electronic and optical properties. The sulfide chemistry makes it of particular interest in photocatalysis, solid-state chemistry, and emerging semiconductor device research where cerium's variable oxidation states and light-interaction properties can be exploited.
