    摘要： Self-assembled photonic crystals, including large sphere planar opals, infiltrated planar opals and inverted planar opals, as well as methods for manufacturing same are provided. Large sphere planar opals are manufactured according to a method comprising the steps of: synthesizing monodisperse silica spheres, wherein each of the silica spheres has a diameter greater than or equal to about 400 nanometers; purifying the silica spheres; and self-assembling the silica spheres into a plurality of ordered, planar layers on a substrate. Infiltrated planar opals may also be manufactured by further processing the large sphere planar opal by sintering the planar opal and infiltrating the planar opal with a predetermined material. Inverted planar opals may further be manufactured by removing the silica spheres from the infiltrated planar opal. Various modifications to the substrate and planar opal are also provided to enhance the properties of these photonic crystals.

    摘要： A method for manufacturing high-quality Mn-doped nanocrystals is provided. The method generally comprises the steps of: (a) combining an organometallic manganese precursor with an organometallic Group II precursor and an organometallic Group VI precursor to provide a precursor mixture; (b) diluting the precursor mixture with a dilution solvent to provide an injection mixture; (c) heating a coordinating solvent; (d) stirring the heated coordinating solvent; and (e) injecting the injection mixture into the heated coordinating solvent while the heated coordinating solvent is being stirred. The invention is particularly useful for manufacturing high-quality, Mn-doped zinc selenide (ZnSe) nanocrystals, high-quality, Mn-doped zinc sulfide (ZnS) nanocrystals, and high-quality, Mn-doped zinc telluride (ZnTe) nanocrystals.

    摘要： A method for patterning materials according to a predetermined, three-dimensional pattern, as well as patterned materials produced by said methods, are provided. A template is prepared comprising a template material, the template having a plurality of pores therein, the plurality of pores comprising a negative of the predetermined, three-dimensional pattern. Colloidal nanocrystals sufficient to fill the pores in the template are also prepared. The pores in the template are filled with the colloidal nanocrystals. A quantum-dot solid is formed from the colloidal nanocrystals within the pores in the template, such that the colloidal nanocrystals are concentrated as close-packed nanocrystals within the pores in the template in the predetermined, three-dimensional pattern. If desired, a conventional solid may be obtained by sintering the close-packed nanocrystals within the pores of the template.
