AbstractOur study describes a convenient one-step synthesis of ZnSe and ZnTe nanocrystals (NC) whose sizes and shapes are precisely tuned by varing the growth temperature or stabilizing surfactants. We utilized molecular precursors, bis(phenylselenolate or phenyltellurolato)zinc -N,N,N',N'-tetramethylethylenediamine (TMEDA), which effectively produce 0-dimensional sphere or 1-dimensional nanorods of ZnSe or ZnTe, respectively. Nanocrystals are highly monodispersed and luminescent; the emission wavelength varies over a wide range depending on the particle size. This study constitutes a nice demonstration of direct size and shape controlled synthesis of semiconductor nanocrystals and this method can be extended to the synthesis of nanocrystals of other materials.

Shape-controlled gold nanostructures were successfully synthesized in an aqueous solution by a one-step, non-templated thermal reduction method through heating of a poly(vinylpyrrolidone)/HAuCl4 aqueous solution. Poly(vinylpyrrolidone) (PVP) serves as both the stabilizing surfactant and reducing agent for the controlled synthesis of gold nanostructures with different shapes. Upon adjusting the chain-length and the concentration of the PVP, decahedral, icosahedral and platelike gold nanostructures with dominating distribution were fabricated, respectively, with the ratio of terminating OH groups at the polymer to Au ions as an important experimental parameter. The results suggest that the morphology of the gold nanostructures could be tuned by this method. The successful preparation of gold nanostructures exemplifies a very facile, effective, and generic strategy for fabrication of gold nanoparticles with various shapes.
