Nanomaterial’s especially metal oxide nanoparticles have recently been of interest in many fields such as physics, biology, and medicine. This work employs Pulsed laser ablation in liquid as a clean and versatile technique for synthesizing copper oxide nanoparticles that produce high-quality materials with minimal chemical interference. Copper plates were treated in deionized water using laser energy density to produce copper nanoparticles at two different energy densities of 400 and 800 mJ. Copper oxide nanoparticles categorized by X-ray diffraction method, UV-visible spectroscopy and scanning electron microscopy (SEM). Changes in absorption spectra and subsequent UV-visible spectroscopy were observed for particle size, with a redshift at greater laser intensity (650 nm for 800 mJ compared to 600 nm for 400 mJ). X-ray diffraction (XRD) result presented this material as having a monoclinic crystalline structure with particle size estimated to be between 30 and 60 nm (34.626° and 34.714° 2θ for 400 mJ; 31.49° and 66.45° 2θ for 800 mJ). Specific morphological analyses through SEM showed products contained elongated nanoflake-like shaped particles extending to 800 mJ that aggregated into a rough structure which boost their catalytic effectiveness. These results confirm application for photocatalytic activities, antibacterial activity, and enhanced biomedical science by controlling size, optical, structure, and morphology.
