摘要:Sonochemical synthesis methods of particles (e.g., nanoparticles, microparticles, quantum dots) in emulsion reaction mixtures are described herein. The methods allow for control of the bulk temperature of the reaction mixtures to minimize the effects of solvent temperature increases. The sonochemical synthesis methods (e.g., in emulsion reaction mixtures) offer efficient, accelerated, and controllable pathways towards the on-demand synthesis of complex materials.

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.

摘要:Common approaches to synthesizing alloyed quantum dots employ high-cost, air-sensitive phosphine complexes as the selenium precursor. Disclosed quantum dot synthesis embodiments avoid these hazardous and air-sensitive selenium precursors. Certain embodiments utilize a combination comprising a thiol and an amine that together reduce and complex the elemental selenium to form a highly reactive selenium precursor at room temperature. The same combination of thiol and amine acts as the reaction solvent, stabilizing ligand, and sulfur source in the synthesis of quantum dot cores. A non-injection approach may also be used. The optical properties of the quantum dots synthesized by this new approach can be finely tuned for a variety of applications by controlling size and/or composition of size and composition. Further, using the same approach, a shell can be grown around a quantum dot core that improves stability, luminescence efficiency, and may reduce toxicity.

标题:Transformative synthesis of semiconductor nanoclusters with atomic precision via metal-ligand coordination exchange

摘要:Precision nanosynthesis is crucial for atomic engineering in nanostructures and mechanistic understanding of nanoscale reactions. But it is a daunting task due to emerging complexities in nanostructures and nanosynthesis. Here, we report the precision synthesis of semiconductor nanocluster via synergizing coordination, cluster, and colloidal chemistry at the nanoscale. In particular, by employing Cu26Se13(PEt2Ph)14 cluster and Cdl2(PPr3)2 coordination complex as precise precursors in colloidal cation exchange reaction, an atomically precise Cd26Se17I18(PPr3)10 cluster is produced at near- unity yield. X-ray crystallography reveals that the child CdSe cluster inherits its icosahedral-packed anion lattice and halide-phosphine-rich surface from parent cluster and complex respectively and further evolves into an enlarged structure. The hybridization of achiral precursors leads to chiral CdSe clusters co-crystallized as a 1:1 mixture of enantiomers. In-situ optical spectroscopy unveils that the reaction proceeds with well-defined pathways. Based on charge and coordination conservations, the structure of child cluster can be atomically linked to precursors via a series of transformations including surface coordination exchange, intra-cluster reorganization, and inter-cluster digestive ripening. The precision nanosynthesis with atomically defined precursors, pathways, and products is expected to further rationalize and diversify nanochemistry.

标题 :Solvents and new method for the synthesis of CdSe semiconductor nanocrystals

摘要:New methods for the synthesis of nanocrystals/quantum dots are disclosed. The methods comprise use of reasonably-priced and commercially available heat transfer fluids (such as Dowtherm® A) as solvents to synthesize CdSe nanocrystals. Separation of nucleation and growth is achieved by quenching the reaction solution with relatively cold (room temperature) solvent to lower the solution temperature. Quenching may be followed by raising the solution temperature, to allow controlled growth to take place.
