Rare earth phosphonium vanadate phosphor and a method of manufacturing

Excellent light emission characteristics, the preferred rare earth phosphotransferase vanadate phosphor in terms of industrial production, and a production method thereof. Rare earth phosphonium vanadate phosphor, on the particle surface, includes at least the primary particles are formed linear uneven pattern including a plurality of parallel ridge each other. A method of manufacturing a rare earth phosphonium vanadate phosphors, after generating a mixture of rare earth phosphosilicate vanadate phosphor and alkali metal vanadates, is to remove the vanadate of an alkali metal .
