· JVASP-22904· K2SmF5

K2SmF5 is a fluoride ceramic compound containing potassium and samarium, belonging to the family of rare-earth fluoride ceramics. This material is primarily investigated in research contexts for optical and photonic applications, where rare-earth fluorides are valued for their transparency in the infrared spectrum and potential as host matrices for rare-earth dopants. Engineers consider K2SmF5 and related samarium fluorides for specialized applications requiring infrared transmission, luminescent devices, or as precursor materials in solid-state laser systems and optical fiber development.
