    摘要： Disclosed are a new composite material and a process for synthesizing highly charged, highly monodisperse, core-shell particles with high refractive index cores, as well as stable, long lasting crystalline colloidal arrays (CCAs) formed thereof. A preferred embodiment of the core particle can be highly monodisperse zinc sulfide (ZnS) particles and a preferred embodiment of the shell can be highly charged polyelectrolytes. The CCAs formed thereof are charge stabilized photonic crystals that shows distinctive first and second order Bragg diffraction peaks whose locations vary over a wide spectral region from UV through visible to IR, with unusually strong intensity and broad band width due to the high index of refraction. These high refractive index particles are useful in applications such as optical filters, optical coatings, cosmetics and photonic crystals sensors and devices.

    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： Metal sulfides are prepared by reacting a compound of the metal and an oxygen-containing anion, with a source of carbonyl sulfide. The resulting metal sulfide is not contaminated by hydrogen, as in the form of hydroxides, and is suitable for use in photoluminescence and electroluminescence applications. The starting material is preferably a metal oxalate, which may be appropriately doped, and the source of the carbonyl sulfide is preferably a mixture of carbon monoxide and sulfur dioxide (to produce a reducing mode) or a mixture of carbon dioxide and carbon disulfide (to produce an oxidizing mode). Oxyanions that decompose to a produce a nascent oxygen anion, as does the oxalate, are preferred, as they can be reacted to achieve a high conversion rate to the sulfide.
