The effect of H2O and PEG on the morphologies of ZnO nanostructures synthesized under microwave radiation

ZnO nanoparticles and nanorods were synthesized from Zn(NO3)2·6H2O and NaOH in H2O and in different molecular weights (MWs) of polyethylene glycol (PEG) using 180 W microwave radiation. The phase was detected using X-ray diffraction (XRD) and selected area electron diffraction (SAED). The diffractio...
