    摘要: An embodiment of the invention is a device for photo-stimulated color emission having at least one plurally doped semiconducting nanoparticle comprising at least one semiconducting material and a plurality of at least one dopant coupled with an irradiation source such that the plurally doped semiconducting nanoparticle emit electromagnetic radiation at two or more wavelengths where the intensities of the emissions depend on the intensity of the irradiation. In an embodiment of the invention, the plurally doped semiconducting nanoparticle can be a doped core/shell nanoparticle where the plurality of dopants can reside in exclusively the core, exclusively the shell, or in both the core and shell.

    摘要: The present invention concerns size- and shape-controlled, colloidal superparticles (SPs) and methods for synthesizing the same. Ligand-functionalized nanoparticles such as nonpolar-solvent-dispersible nanoparticles, are used, and the solvophobic interactions can be controlled. Advantageously, supercrystalline SPs having a superlattice structure, such as a face-centered cubic structure, can be produced. Further, the methods of the invention can provide SPs that self-assemble and are monodisperse. The SPs can be doped with organic dyes and further assembled into more complex structures.
