Abstract: A method of making a luminescent nanomaterial having a plurality of nanoparticles. The luminescent nanomaterial includes at least one lanthanide group metal phosphate and at least one lanthanide series dopant, wherein each of the plurality of nanoparticles has a predetermined morphology. The luminescent nanomaterial has a high quantum efficiency and a high absorption value. The method yields a variety of morphologies and sizes of the plurality of nanoparticles. The particles size of the luminescent material varies from tens of nanometers to a few hundred of nanometers.
Abstract: A material comprising a plurality of nanoparticles. Each of the plurality of nanoparticles includes at least one of a metal phosphate, a metal silicate, a metal oxide, a metal borate, a metal aluminate, and combinations thereof. The plurality of nanoparticles is substantially monodisperse. Also disclosed is a method of making a plurality of substantially monodisperse nanoparticles. The method includes providing a slurry of at least one metal precursor, maintaining the pH of the slurry at a predetermined value, mechanically milling the slurry, drying the slurry to form a powder; and calcining the powder at a predetermined temperature to form the plurality of nanoparticles.
