摘要： This invention relates to the controlled growth of uniform octapod-shaped colloidal nanocrystals and use thereof. These octapod-shaped nanocrystals can be applied in many fields of technology. This represents the first approach reported so far for the predictable and controlled fabrication of octapod-shaped nanocrystals. The synthesis approach is applicable to a broad range of materials, such as group II-VI semiconductor nanocrystals but is not limited to these materials. Using several cation exchange and oxidation procedures, we also demonstrate in this application that extremely uniform octapod-shaped nanocrystals of other materials can be synthesized, including various semiconductors, metals and insulators.

摘要： A method of producing a lasing microsource of colloidal nanocrystals. The method includes the steps of preparing a nanocrystal solution in a solvent; depositing at least a drop of the nanocrystals solution with a drop volume below 1 nl on a flat substrate; and evaporating the solvent to dryness thereby to obtain at the edge of the evaporated drop a single annular stripe including a domain wherein the nanocrystals are arranged in an ordered array, wherein the ordered nanocrystals in the domain constitute an active region capable of lasing and the radially inner and outer edges of the stripe define a resonant cavity in which the active region is inserted.
