Abstract
Provided is a rare earth phosphovanadate phosphor that is excellent in emission characteristics and preferred also from the viewpoint of industrial production, and a production method thereof. The rare earth phosphovanadate phosphor includes at least a primary particle in which a linear uneven pattern including a plurality of ridge lines parallel to each other is formed on the surface of the particle. Further, the method for producing a rare earth phosphovanadate phosphor involves generating a mixture of a rare earth phosphovanadate phosphor and an alkali metal vanadate, and removing the alkali metal vanadate.
