Abstract
Metal nanoparticles (NPs) of silver (Ag), copper (Cu), zinc oxide (ZnO), cadmium oxide (CdO) and tin (Sn) were synthesized by laser ablation of a solid target in de-ionized water (DI). X-ray diffraction patterns showed the formation of AgO, Ag, Cu, ZnO, CdO, and Sn NPs. Absorbance spectrum of the produced nanoparticles was measured by UV-Vis spectrophotometer which showed that Ag and CdO NPs shifted to the short wavelength (blue shift), indicating the formation of NPs with smaller sizes, whereas CuO showed the formation two peaks. ZnO and Sn NPs shifted to the long wavelength (red shift) which indicates the formation NPs with larger size. Zeta potential results proved that ZnO nanoparticles were more stable (-26.53mV) than the other metal nanoparticles, while CdO nanoparticles had more aggregation (-16.65mV).
Highlights
Nanotechnology demands the ability to control features at the nanoscale (10−9 m) [1]
Pulse laser ablation in deionized water was prepared for Ag, Cu, Zn, Sn, and Cd and their characterization was studied
Figure-2 shows the formation of AgO and Ag NPs prepared by pulsed-laser ablation in liquid (PLAL) of an Ag target which has a polycrystalline structure of monoclinic and cubic phases
Summary
Nanotechnology demands the ability to control features at the nanoscale (10−9 m) [1]. Figure-2 shows the formation of AgO and Ag NPs prepared by PLAL of an Ag target which has a polycrystalline structure of monoclinic and cubic phases. Figure-3 shows that Cu NPs have a polycrystalline structure and a cubic phase, while there was a matching between the orientation of the Miller Indices (hkl) to each peak for Cu NPs with (111) and (200) planes.
