About Europium orthovanadate
Europium orthovanadate is a thermodynamically stable crystalline compound that occupies a prominent position on the convex hull of its constituent elements. As a semiconducting material, it is highly valued for its structural integrity and its ability to host rare-earth ions, making it a critical subject in solid-state chemistry and materials research.
Its utility stems from its robust lattice structure, which supports efficient luminescence when doped with various activators. This makes the compound a standard host material for advanced optical applications, particularly in the development of high-performance phosphors and specialized laser host crystals.
Key Properties
Cross-validated computational properties for Europium orthovanadate, 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.
