Abstract

Precipitation of gold nanoparticles is achieved in silicate glass doped with Au ions by UV femtosecond laser irradiation and subsequent annealing treatment. The influences of different power and annealing temperature on the formation of Au nanoparticles are studied: the higher the laser power, the larger the diameter of Au nanoparticles. As the annealing temperatures increase, the colors of the samples are from light purple to purple-red. The peaks of absorption spectrum of the nanoparticles move to the long wavelength.
