· JVASP-45361· Er2S3

Er2S3 is an erbium sulfide ceramic compound belonging to the rare-earth chalcogenide family, which combines erbium (a lanthanide element) with sulfur to form a stable ionic ceramic. While primarily of research interest, Er2S3 and related rare-earth sulfides are investigated for potential applications in high-temperature optics, luminescent materials, and specialized electronic devices where rare-earth-doped ceramics offer unique optical or thermal properties. This material represents an experimental composition within a family of compounds studied for niche applications requiring specific combinations of thermal stability, optical transparency in infrared wavelengths, and rare-earth functionality.
