MORPHOLOGICALLY AND SIZE UNIFORM MONODISPERSE PARTICLES AND THEIR SHAPE-DIRECTED SELF-ASSEMBLY

WIPO Patent Application WO/2012/091778

A3

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. Methods of making and methods of using the monodisperse particles are disclosed.
