摘　　要：In Ag^＋ and Au^3＋ co-doped silicate glass sample, we realized controllable precipitation and dissolution of Ag and Au nanoparticles. A new method was proposed for separate precipitation of Ag and Au nanoparticles in different areas of the same sample through femtosecond laser irradiation and further annealing; different colors were obtained in the same glass. We also studied the laser dissolution of Ag and Au nanoparticles in the Ag^＋ and Au^3＋co-doped silicate glass. The mechanism of the phenomena we observed was discussed briefly.In Ag^＋ and Au^3＋ co-doped silicate glass sample, we realized controllable precipitation and dissolution of Ag and Au nanoparticles.
