Abstract

Abstract In this work, the generation of Al-Cu content nanocomposites were done by using Pulsed Nd:YAG laser (1064 nm) ablation in water confined plasma. At first, the Al content nanoparticles were fabricated and characterized. Then, copper target was merged into the Al content suspension and the laser irradiation on the target was done. On the other hand, a sample with copper target in the water medium was prepared, separately. The characterization of the nanoparticles performed by transmission electron microscopy (TEM), spectrum absorption and selected area electron diffraction (SAED) and optical absorbance. The SAED of the Al content nanoparticles shows crystallographic surfaces like bulk Al while the SAED of Al-Cu content nanocomposite did not show a regular crystalline structure. Absorbance wavelength dependence of the three produced suspensions was investigated. It shows the Cu - Al content suspension showed different behaviors in comparison with Al content and Cu content suspensions.
