Abstract

In this study, copper nanoparticles (CuNPs) were prepared using the pulsed laser ablation method, and the study was conducted under the effect of changing the liquid medium (ethanol, deionized water, distilled water) with a number of pulses (700p/s) and using a (Q-switched Nd-YAG) laser. At a wavelength of 532nm and an energy of 100mJ, the results of the samples prepared in a medium (ethanol, distilled water, deionized water) showed the average radii of CuNPs (58.3, 61.6, 46.1 nm, respectively) with a spherical shape. The spectrum of copper at (3250 to 3550 ) is mainly due to the expansion of (O-H) the clear hydroxyl group and under the conditions of the three solvents (ethanol, deionized water, distilled water). The XRD results showed that the CuO nanoparticles are free of impurities and crystallized High and the crystallite size was calculated at 2theta (20.094, 19.949, 38.045) nm for the samples in (deionized water, distilled water, and ethanol), respectively.
