Pulsed Laser Ablation Produced Copper Nanoparticles (CUO NPS): The Influence of Time

Copper nanoparticles were synthesized using laser ablation method by the reduction of copper plate in the presence of distilled water. Effects of time as the laser hits on the copper target were increased, the amount of CuO NPs in the distilled water also increased. EDAX confirms the existence of CuO NPs elements. The metallic nanoparticles have unique optical properties known as Surface Plasmon Resonance (SPR) at 635 nm which can be utilized to enhance the light harvesting performance in many applications. The noble metals of copper have the ability to support surface plasmon resonance which can be used to enhance the efficiency of any device.
