Abstract: A method for producing highly monodisperse nanocrystals comprising the steps of: a) preparing a precursor comprising a metal ion and a coordinating ligand; b) dissolving the precursor in a solvent mixture comprising coordinating solvent and optionally non-coordinating solvent; c) raising the temperature of the step b mixture into the range from 150° C. to 350° C.; d) adding a chalcogen to the step c heated mixture whereby the chalcogen reacts with the precursor; e) lowering the temperature of the step d mixture to stop the reaction; and e) maintaining the step e cooled mixture for sufficient time at sufficient temperature to narrow the size distribution of the nanocrystals.

Abstract: A method for preparing cadmium sulfide nanocrystals emitting light at multiple wavelengths. The method comprises the steps of (a) mixing a cadmium precursor and a dispersant in a solvent that weakly coordinates to the cadmium precursor, and heating the mixture to obtain a cadmium precursor solution, (b) dissolving a sulfur precursor in a solvent that weakly coordinates to the sulfur precursor to obtain a sulfur precursor solution, and (c) feeding the sulfur precursor solution to the heated cadmium precursor solution maintained at a high temperature to prepare cadmium sulfide crystals, and growing the cadmium sulfide crystals. Further, cadmium sulfide nanocrystals prepared by the method. The cadmium sulfide nanocrystals have uniform size and shape and can emit light close to white light simultaneously at different wavelengths upon excitation. Due to these characteristics, the cadmium sulfide nanocrystals can be applied to white light-emitting diode devices.

Abstract: Dendron ligands or other branched ligands with cross-linkable groups were coordinated to colloidal inorganic nanoparticles, including nanocrystals, and substantially globally cross-linked through different strategies, such as ring-closing metathesis (RCM), dendrimer-bridging methods, and the like. This global cross-linking reaction sealed each nanocrystal within a dendron box to yield box-nanocrystals which showed dramatically enhanced stability against chemical, photochemical and thermal treatments in comparison to the non-cross-linked dendron-nanocrystals. Empty dendron boxes possessing a very narrow size distribution were formed by the dissolution of the inorganic nanocrystals contained therein upon acid or other etching treatments.

Abstract: A mixed melt, which contains urea and/or a urea derivative and contains a sulfur source and a zinc source, is prepared. A temperature of the mixed melt is raised, and a precipitate of zinc sulfide is thereby formed. The temperature of the mixed melt is raised even further, and a solid material containing the zinc sulfide is thereby formed. The solid material is fired, and organic constituents contained in the solid material are thus removed. Zinc sulfide particles having uniform particle size and free from inclusion of impurities are thus produced without any precipitant being added.
