Generation of Al Nanoparticles via Laser Ablation in Deionized Water with Structural and Morphological Study

In this work, Al nanoparticles were generated using Pulsed Nd : YAG laser (1064 nm) ablation in water confined plasma. Productions were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD) and selected area electron diffraction (SAED). Laser ablation of the Al target in deionized water leads to fabrication core-shell type structure due to partial oxidation in the water medium. The Nano sized core-shells are spherical in shape and have mean size similar to 16 nm. NPs were in the crystalline form as bulk Al. Obviously, the chemical composition of the Nano sized core-shells surface must be Al2O3 because of water medium.
