· JVASP-53137· NaHo2F7

NaHo2F7 is a rare-earth fluoride ceramic compound containing sodium and holmium, belonging to the family of lanthanide fluoride materials studied for advanced photonic and thermal applications. This material is primarily of research interest rather than established industrial production, with potential applications in optical systems, thermal management components, and specialized ceramics where rare-earth fluorides offer unique transparency, thermal stability, or luminescent properties. Rare-earth fluoride ceramics like this compound are explored as alternatives to conventional oxides when lower phonon energies, improved optical transmission, or enhanced thermal conductivity in specific wavelength ranges are required.
