Gold and silver nanoparticles were prepared as colloidal in water by pulsed laser ablation method. Nanoparticles are characterized by UV Vis, FTIR and Atomic absorption spectroscopy. Absorbance spectrum has been measured as a function of time and laser energy. Both types of colloidal nanoparticles showed plasmonic absorption in the visible spectrum at 525 nm and 400 nm for Au and Ag nanoparticles, respectively.
