With the development of modern science and technology, the preparation andcharacterization of metal nanoparticles have been an active area of investigationbecause of their unique electronic and optical properties. Due to their properties aresubstantially distinct from those both the bulk phase and individual molecules, thesenanoparticles would be potentially applied in biological labeling, surface-enhancedRoman, solar cell, electrochromic devices, electroluminescent films, nonlinearoptical switches and high...
