· JVASP-51357· Yb2S3

Yb2S3 is a rare-earth sulfide ceramic compound composed of ytterbium and sulfur, belonging to the family of lanthanide chalcogenides. This material is primarily of research and specialized industrial interest, valued for its optical and thermal properties in high-temperature applications and potential use in photonic devices where rare-earth dopants provide luminescence or up-conversion capabilities. Unlike common oxides, sulfide ceramics like Yb2S3 offer extended infrared transparency and can function as host materials for lanthanide-based light emission, though their chemical stability and cost make them less common than oxide alternatives in mainstream engineering.
