Silicon metal, colloidal silica from

The absorption band at about 540 nm was due to the surface plasmon resonance of tire Au nanoparticles. The appearance of the plasmon band indicates that the colloidal Au particles have reduced in the silica matrices by grafted silicon hydride groups. It was found that the surface plasmon band increased in intensity with growth of particle sizes. In general, the intensity enhancement of absorption band results from increase of metal particles size, combining with band shift. [Pg.476]
