Formation mechanism of ZnO nanorods produced by the electromagnetic levitational gas condensation method

The Electromagnetic Levitational Gas Condensation (ELGC) method was used to synthesize ZnO nanorods. In this paper, the formation mechanism of the synthesized nanorods is discussed. The ELGC method involved vaporization of the levitated Zn specimen, with subsequent condensation and oxidation of nuclei formed under Ar or He–0.2Ar and O2O2 atmospheres. The particles were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The presented results showed that the [0001]-oriented ZnO nanorods were directly produced by the ELGC process under different process conditions.
