Abstract (en)
[origin: WO2005022120A2] A process for producing nanocrystals and nanocrystals produced thereby . The process comprises contacting a metal precursor with a mixture, which includes a coordinating solvent and optionally a surfactant and metal catalyst, to form a first precursor mixture. The process also comprises heating the first precursor mixture to a first temperature and contacting the first precursor mixture with a second precursor mixture, which may be a Group V or Group VI precursor, to form a reaction mixture at a second temperature. The process further comprises heating the reaction mixture at a third temperature to grow nanocrystals, whereby the second temperature is no more than about 15°C lower than the first temperature. The figure is a flowchart depicting the nanocrystal production process.
