· JVASP-35947· Y2ZnS4

Y2ZnS4 is a rare-earth zinc sulfide ceramic compound combining yttrium with zinc and sulfide ions, belonging to the family of mixed-metal sulfide ceramics. This material is primarily of research and development interest rather than established in high-volume production, with potential applications in optoelectronics, photocatalysis, and specialized optical coatings where rare-earth-doped sulfides offer tunable luminescence and band-gap properties. Engineers would consider Y2ZnS4 when conventional oxide ceramics or single-component sulfides are insufficient, particularly in applications requiring rare-earth photonic functionality or environments where sulfide chemistry provides advantages over oxides.
