· JVASP-22958· KSmF4

KSmF4 is a potassium samarium fluoride ceramic compound belonging to the rare-earth fluoride family. This material is primarily investigated in optics and photonics research, particularly for solid-state laser applications and luminescent devices that exploit samarium's unique optical properties. While not yet widely established in high-volume industrial production, KSmF4 represents a promising candidate for next-generation laser hosts and optical coatings where rare-earth dopants are needed for specific wavelength emission or fluorescence applications.
