Studying the effect of irradiation time in preparing zinc oxide nanoparticles prepared by microwave method
Source abstract
Abstract
Zinc oxide nanoparticles were prepared by microwave method by dissolving zinc nitrate salt (Zn(NO3) 2 .6H2O) in deionized water. The prepared nanoparticles were characterized by X-ray diffraction method (XRD ), Field Effect-scanning electron microscopy (FE-SEM ), infrared spectroscopy (FTIR ), and UV-visible spectroscopy(UV.Vis.). The results of the structural tests showed that the prepared nanomaterial was of a hexagonal wurtzite structure with an ideal growth along the C- axis with an average particle size of about 24 nm. While the images of the(FESEM) showed that the nanoparticles were arranged in the form of nanorods and they had an irregular distribution The purity of the samples was confirmed(Zno) by EDAX data . And the results of FTIR showed distinct locations at the band (464 to 430 cm-1 ), which indicates the characteristic stretching mode of the Zn–O bond. The results UV-Vis. showed that the prepared materials have a band gap between 3.23 and 2.21 eV.
