Method for preparing rare-earth doped fluoride nanoparticles
The invention is directed to a process of combining an aqueous solution of a fluoride with an aqueous solution of a host multi-valent metal salt and an aqueous solution of a salt forming a reactant mixture resulting in a precipitate of aqueously insoluble rare-earth doped multi-valent metal fluoride nanoparticles.
