摘要：

The morphology of unprecedented star-shaped gold nanoplates and the crystal growth process where the star-shaped nanoplates have been prepared via the reduction of HAuCL4 by L-ascorbic acid at room temperature in the presence of poly(N-vinyl-2-pyrrolidone) (PVP) was described. The morphology of star-shaped nanoplates was found to be attributed to their atomic structures. A selected area electron diffraction (SAED) pattern of the star-shaped nanoplate lying flat on the substrate was shown. Techniques of TEM have revealed that the star-shaped nanoplates were single crystal of flat plate with face and six symmetric hones. The addition of an appropriate nuclear as seed in the reaction solution promote high yield preparation of nanoplates.
