Synthesis of cadmium oxide nanoparticles by pulsed laser ablation in liquid environment

Colloidal spherical nanoparticles of cadmium oxide (CdO) have been prepared by using Nd:YAG pulsed laser ablation [1064 nm, 7 ns, 10 Hz, and 80 ml] of cadmium sheets target immersed on deionized water. The optical properties of prepared CdO nanoparticles were investigated by using UV-vis spectrophotometer. The morphology and structure were analyzed by scanning electron microscopy, transmission electron microscope, Energy dispersive spectroscopy, and X-ray diffraction. The structure of CdO nanoparticles is confirmed to be crystalline and has hexagonal structure. The morphology of CdO nanoparticles is nano spherical particles with diameter approximately 47 nm. Also, the stability of prepared nanoparticles is studied using successive electronic spectra up to 300 min. Each spectrum shows very similar behavior and it could be seen there are no shift in the position of the wavelength maximum. (C) 2017 Elsevier GmbH. All rights reserved.
