SYNTHESIS OF NANOPARTICLES CONTAINING METAL VANADATE (III) Russian patent published in 2009 - IPC C10G31/00 C09K11/82 C09K11/70 B82B3/00 B82B1/00 

FIELD: nanoparticles.

SUBSTANCE: invention relates to the method for obtaining nanoparticles with a diameter of less than 30 nanometers, containing metal vanadate (III). The method includes reaction of reactive vanadate source in reactionary medium, soluble or dispersible in reactionary medium, and reactive salts of metal (III), soluble or dispersible in reactionary medium at warming. The reactionary medium contains water and, at least, one polyol at volumetric ratio from 20/80 to 90/10. The above polyol represents an organic bond having two, three or more hydroxylic groups, admixed with water in the used volumetric ratio and at the used reaction temperature. Nanoparticles containing metal vanadate (III) represent unessentially doped nanoparticles of metal vanadate (III). Dopped nanoparticles are characterised by excellent luminescent properties.

EFFECT: production of nanoparticles containing metal vanadate (III) with a high yield and narrow particle distribution by sizes.
