Plasmonic Absorption of Gold and Silver Nanoparticles in Water
Engineering and Technology Journal,
2014, Volume 32, Issue 6, Pages 1019-1029
AbstractGold 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.
