· JVASP-53435· Sm2ZnS4

Sm2ZnS4 is a rare-earth zinc sulfide ceramic compound combining samarium with zinc and sulfide ions, belonging to the family of chalcogenide ceramics used primarily in photonic and electronic applications. This material is of significant research interest for optical devices, particularly in infrared transmission windows and luminescent applications where rare-earth dopants provide unique optical properties. Its notable advantage over simpler sulfide ceramics lies in the incorporation of samarium, which enables specialized photonic functionality in wavelength regions relevant to telecommunications and thermal imaging systems.
