Figure 1 show the relationship between particle size with the melting point of the gold particles.In general, the geometry. Are determined by the composition and properties of severalSynthesis of materials, and the mechanism of formation. The island together of nanoparticles for metal.Some species, such as the nano particles of the transition metals, structure of the emerging by แตกต่างไป.According to the characteristics of the structure of the original cube crystal structure such cabooctahedron icosahedron.And the decahedron as Figure 2 structure. Or planes of different surface not only makes.Density of surface of atoms are different. But also make the electronic structures, commitment, and chemical reaction.Different control the size, shape and structure of nano particles of metal technology is important.The cause relation greatly between these variables with optical properties commercial electricity.The reaction, etc.
