NaYOFN

NaYOFN is a rare-earth-doped fluoride ceramic compound belonging to the family of oxyfluoride glasses and crystalline materials, where yttrium and sodium form the host lattice with fluoride anions. These materials are primarily investigated in photonics and laser applications, particularly as host matrices for rare-earth ion dopants (like erbium or ytterbium) that enable efficient light emission and amplification in the near-infrared spectrum. The oxyfluoride structure combines the optical transparency and thermal properties of fluoride ceramics with the mechanical stability of oxide ceramics, making it attractive for integrated photonic devices, fiber amplifiers, and solid-state laser research where conventional silicate or pure fluoride hosts present trade-offs in performance.
