· JVASP-21453· KRb2YF6

KRb₂YF₆ is a fluoride-based ceramic compound belonging to the elpasolite family of materials, characterized by its mixed-cation fluoride structure. This material is primarily studied in research contexts for photonic and optical applications, where fluoride ceramics are valued for their transparency in the infrared region and low phonon energy, making them candidates for laser hosts and optical components. KRb₂YF₆ is notable within fluoride ceramics for its thermal stability and potential as a host matrix for rare-earth ion doping, though it remains largely in the development phase compared to more established optical ceramics.
