| Abstract | ||
| In this paper, the pulsed ablation laser in liquids (PLAL)method was used to obtain copper nanoparticles from material copper, One of the first signs of nanoparticle production or generation using the pulsed laser is a change in the color of the sample's solution as the concentration of nanoparticles increases. In our study, deionized distilled water with a volume of 5 mL was used to prepare the samples with energy (300, 500)mj. With number of pulsed (50, 100, 150, 200) pulse respectively. We noticed a change in the color of the solution to a dark white color, indicating the presence of silver nanoparticles. In another side study the obsorbancy and transmission by using UV-Visible spectroscopy, the peaks of all samples were at wave length at (250-260) nm. This confirms that nanoparticles have been obtained from silver material. The determined mean energy gab for direct transition allowed of the samples is 2.74 eV. | ||
