Cs2NaYF6 is a fluoride-based ceramic compound containing cesium, sodium, and yttrium—a rare-earth-doped material belonging to the family of elpasolite (double perovskite) fluorides. This material is primarily investigated in research contexts for its potential as an optical or luminescent ceramic, leveraging the photonic properties imparted by yttrium and the structural stability of the fluoride host lattice. Compared to oxide ceramics, fluoride hosts offer lower phonon energies and reduced quenching, making them attractive for applications requiring efficient energy transfer or emission across the ultraviolet to near-infrared spectrum.
