About Sodium yttrium fluoride
NaYF4 is a thermodynamically stable inorganic fluoride that functions as a wide-band-gap insulator. Its structural reliability and chemical robustness make it a foundational material in materials science, particularly for applications requiring high optical transparency and stability.
Due to its ability to host various dopants, this compound is extensively researched for its role in photonics and energy-transfer processes. It serves as a critical platform for developing materials that manipulate light at the nanoscale, benefiting from its well-defined crystalline phases.
Key Properties
Cross-validated computational properties for Sodium yttrium fluoride, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
