标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

标 题 :Method for synthesizing nanoparticles of metal sulfides
发明人：HYEON TAEGWHAN
摘要:A synthetic method of fabricating highly crystalline and uniform nanoparticles of metal sulfides, doped metal sulfides, and multi-metallic sulfides disclosed, using no-toxic and inexpensive reagents. A typical synthetic method comprises the steps of, synthesis of metal-surfactant complexes from the reaction of metal precursors and surfactant, addition of sulfur reagent to the solution containing said metal-surfactant complexes followed by heating to high temperature, aging at that temperature to produce metal sulfide nanoparticles and completing the formation of synthesis of nanoparticles metal sulfides and multi-metallic sulfides by adding a poor solvent followed by centrifuging.

标题 :Fabrication of high aspect ratio core-shell CdS-Mn/ZnS nanowires

摘要:Compositions and methods for fabrication or synthesis of high aspect ratio (up to >150) CdS:Mn/ZnS core/shell nanowires (CSNWs) is disclosed for the first time. The CSNW solvothermal synthesis involved two steps—the formation of Mn doped CdS core followed by the growth of a ZnS outer shell. The nanowire growth process is engineered in such a way that the ZnS layer grows radially onto the prematurely grown CdS:Mn core prior to the formation of its well faceted surface. Transmission electron microscopy (TEM) and other characterization techniques confirmed the formation of uniform, thin (5-8 nm in diameter) CSNWs with high aspect ratio up to >150. This solvothermal method is simple, versatile and useful in a large scale production process to synthesize thin ultra-long CSNWs with and without dopants.
