| Abstract | ||
| The objective of this work is to synthesize of ZnO nanoparticles by sol-gel method and silver nanoparticles by laser ablation. An aqueous zinc nitrates was dissolved in distilled water and then stirred for 30 mints. Starch was also dissolved in water and stirred at 60°C for 90 minutes. The two solutions were mixed and stirred for 12hr at 80°C in an oil bath. The gel obtained was calcined in an oven at 700°C for one hour to obtain ZnO nanoparticles. Square silver piece of 5g was placed in a glass with a current of nitrogen gas. The silver piece was then subjected to pulse laser beam of 532nm wavelength and 250 mW. Thereafter, the glass was washed with methanol and put under the sun, and then the silver powder was put in an oven at 60°C for 14 hrs until obtaining silver nanoparticles powder. UV, SEM, and XRD analyses were used to characterize the powders prepared, and it was found that the average size of ZnO particles was 13.8nm and for an Ag particle size was 12.4nm. | ||
