The Ag nanoparticles colloid was prepared by pulsed laser ablation for different time in 10 ml distilled water without any surface active agent,and it was analysed by means of UV-visible spectrophotometer and transmission electron microscopy (TEM).The results showed that the ablation efficiency and absorbance increased fast and shift to higher energies,the average diameter of Ag colloidal nanopartides increased,and the size distribution narrowed with increasing the ablation time from 5 to 10 minutes.Then the ablation efficiency and absorbance as well as the average diameter increased slowly,and the size distribution broaden from 10 to 20 minutes.Finally,the ablation efficiency and absorbance increased,the average diameter decreased and the size distribution narrowed again from 20 to 25 minutes.
