Abstract
Green nanotechnology, which involves nanoparticle synthesis using plants, has garnered significant attention among researchers due to its environmentally friendly approach that eliminates the use of toxic chemicals, making it an ecofriendly alternative to conventional physical and chemical methods. In this study, zinc oxide nanoparticles (ZnO-NPs) were synthesized using lemon extract and zinc nitrate. The Lemon extract mediated synthesis of ZnO particles was thoroughly investigated through various analytical methods, such as Fourier Transform Infrared Spectroscopy (FTIR), FE-SEM, Transmission Electron Microscopy (TEM), and X-ray diffraction (XRD). The XRD analysis revealed that the ZnO-NPs possessed a hexagonal (wurtzite) shape with an average size of 49 nm, as indicated by changes in the intensity peaks. TEM studies showed that the ZnO NPs exhibited an agglomerated and spherical shape. Respectively. This ecofriendly synthesis method holds promise for a wide range of applications, including medical applications, as well as its potential use in the preparation of LEDs and solar cells.
