Green synthesis of ZnO nanostructures using Pyrus pyrifolia: Antimicrobial, photocatalytic and dielectric properties

In this study, zinc oxide nanostructures (ZnO NS) were synthesized using Pyrus pyrifolia fruit extract. Biophysical characterization results confirmed that the synthesized materials are crystalline wurtzite ZnO structures. Field emission scanning electron microscopy (FESEM) revealed that the ZnO NS...
