Nanofabrication and characterization of gold metal by Pulsed Laser Ablation in SDS solution

Abstract

Gold nanoparticles were synthesized by pulsed laser ablation (Q-switched Nd:YAG, ?=1064nm, 10 ns pulse duration and E=750 mJ) of pure Au  metal plate immersed in double distilled and deionized water DDDW and other aqueous solution of SDS with various concentrations.Absorbance spectra of the produced nanoparticles solution was measured by uv-vis spectrophotometer, which show single and sharp peak around 525 nm, indicating the produced Au nanoparticles with a narrow size ranging from 5 to 50 nm with almost spherical shape. The morphology and size was estimated by SEM.
