Formation of Gold Nanonetworks and Small Gold Nanoparticles by Irradiation of Intense Pulsed Laser onto Gold Nanoparticles

摘要: Gold nanoparticles with an average diameter of ∼20 nm were prepared in water by laser ablation at 1064 against a gold metal plate it. The thus and those mixed aqueous solution sodium dodecyl sulfate (SDS) irradiated intense pulsed 532 nm. products the examined transmission electron microscopy (TEM) optical absorption spectroscopy. TEM images revealed that nanonetworks much smaller produced selectively proper choice fluence SDS concentration. spectra measured simultaneously showed have wavelength longer than 600 which is assignable to longitudinal plasma oscillation nanonetworks, while (clusters) band visible UV region. Taking advantage characteristic ...
