· JVASP-53580· Yb2CaS4

Yb2CaS4 is a rare-earth sulfide ceramic compound combining ytterbium, calcium, and sulfur, belonging to the family of lanthanide chalcogenides. This material is primarily of research interest for photonic and optoelectronic applications, where its optical properties—particularly luminescence and potential for wavelength conversion—are being explored in laboratory and development settings rather than established industrial production.
