In this study, zinc oxide nanostructures (ZnO NS) were synthesized using Pyrus pyrifolia fruit extract. Biophysical characterization results confirmed that the materials are crystalline wurtzite ZnO structures. Field emission scanning electron microscopy (FESEM) revealed NS cubical, and sizes range 20–80 nm. Transmission (TEM) XRD a crystal lattice spacing of 0.23 nm (101) plane on NS. UV-Visib...
