摘要：

We report the growth of monometallic crystals from reduction of metal sols. In particular the Au system is reported in this work. A number of techniques are applied to the characterization of the crystallites. It is shown that particles from a few nanometers to crystals of 100-mu-m can be prepared with different shapes and morphologies. Particularly conspicuous shapes are those with a 5-fold symetry axis such as icosahedron or decahedron.
