DyOF
DyOF is a stable, wide-band-gap insulating compound composed of dysprosium, oxygen, and fluorine.
About DyOF
Dysprosium oxyfluoride is a stable inorganic compound that exhibits insulating electronic behavior. Its position on the convex hull confirms its thermodynamic robustness, making it a reliable candidate for specialized material applications where chemical stability is paramount. The material has been characterized across multiple structural databases, reflecting significant interest in its crystalline arrangements. As a wide-band-gap insulator, it is particularly well-suited for applications requiring high dielectric performance or optical transparency in specific spectral ranges. Its unique combination of rare-earth dysprosium with oxygen and fluorine provides a distinct platform for exploring luminescent or dielectric properties in solid-state chemistry.
Key Properties
Cross-validated computational properties for DyOF, 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.
