EFFECT OF LASER PULSE ENERGY ON THE GOLD NANOPARTICLES PRODUCED BY LASER ABLATION METHOD

摘要

Laser pulse energy is shown to influence characteristics of Au nanoparticles (NPs) produced by laser ablation. Au NPs were formed with spherical shape and different size depending on the laser pulse energy. UV-Vis-NIR spectroscopy revealed the changes of surface plasmon resonance features with respect to size and number of NPs.
