Size Control of Gold Nanoparticles During Laser Ablation In Liquids With Different Functional Molecules

Over the last decade many papers dedicated to the generation of nanoparticles in liquids using laser ablation have been published. They have shown that the nanoparticles size distribution is dependent of the laser fluence and shifts towards smaller sizes when the surfactant concentration is increased. In this paper an alternative approach is presented that permits the control of the size distribution of gold nanoparticles during laser ablation in aqueous solutions containing different surfactant molecules with different shapes and size.
