Thermal evaporation synthesis and properties of ZnO nano/microstructures using Sn reducing agents

ZnO nano/microstructures have been successfully synthesized via the thermal evaporation mothed using Sn powders as the reducing agents. The as-synthesized products have been systematically studied by X-ray powder diffraction (XRD), Raman spectroscopy (RS), scanning electron microscope (SEM), electron energy-dispersive X-ray (EDX) and ultraviolet-visible spectrum (UV-vis). The results indicate that pure ZnO and Zn₂SnO₄-doped ZnO were collected at the growth temperatures of 600 °C and 750 °C, respectively. Furthermore, the band gap energy of the as-synthesized product is estimated to be smaller than the reported value for ZnO. The Zn₂SnO₄ phase in the ZnO nano/microstructures plays an important role in the optical property.
