Neodymium(III) vanadate is an inorganic compound, a salt of neodymium and vanadic acid with the chemical formula NdVO<sub>4</sub>. It is a paramagnetic solid, pale-blue or silver-gray in appearance. In nanoparticle form it is described as yellow.
Neodymium(III) vanadate is produced by the reaction of hot acidic neodymium(III) chloride and sodium orthovanadate:
Nanoparticles can be prepared by treating an ammonium metavanadate (NH<sub>4</sub>VO<sub>3</sub>) solution with neodymium nitrate and a capping agent.
