Crystal structure analyses of ZnO nanoparticles growth by simple wet chemical method

摘要

We have synthesized ZnO nanoparticles by using simple wet chemical method at calcination temperature of 400° C for 2 hours.Scanning electron microscopy(SEM)and X-ray diffraction(XRD)were performed to analyse morphology and crystal structure of ZnO nanoparticles,respectively.Morphologically,ZnO nanoparticles aggregated formed larger particles.Then,according to the International Center for Diffraction Data(ICDD)number #98-002-9272,the XRD spectra confirmed that the ZnO nanoparticles have polycrystalline hexagonal structure with prefer orientation of(002)and crystallite size in the range 21 nm.
