  • Synthesis of nanoparticles comprising metal (III) vanadate
    Patent number: 8337804
    Abstract: The present invention relates to a method for the production of nanoparticulate metal(III) vanadates or vanadate/phosophate mixed crystals, comprising the reaction in a reaction medium of a reactive vanadate source and optionally a phosphate source dissolvable or dispersible in the reaction medium and of a reactive metal(III) salt dissolvable or dispersible in the reaction medium under heating, wherein the reaction medium contains water and a polyol in a volume ratio of 20/80 to 90/10, and the particles thereby obtained. The synthesis provides a high yield of metal(III) vanadate or vanadate/phosphate having a narrow particle size distribution. Doped embodiments thereof are distinguished by excellent luminescence properties.
