Abstract:
Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape). Also disclosed is a combination of at least two types of monodisperse particles, where each type is a plurality of monodisperse particles having a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology; and where the types of monodisperse particles differ from one another by composition, by size, or by morphology. In a preferred embodiment, the types of monodisperse particles have the same composition but different morphologies. Methods of making and methods of using the monodisperse particles are disclosed.

Claim (Index 10):
The plurality of monodisperse particles of  claim 9 , wherein the up-converting phosphors are selected from the group consisting of sodium yttrium fluoride, lanthanum fluoride, lanthanum oxysulfide, rare earth oxysulfide, rare earth oxyfluoride, rare earth oxychloride, yttrium fluoride, yttrium gallate, gadolinium fluoride, barium yttrium fluoride, and gadolinium oxysulfide.
