Effect of Temperature and Synthesis of ZnO Nanostructures on Zn Plate by Thermal Method

Abstract

ZnO nanostructures were synthesized by thermal evaporation method using Zn metal plate in air. The Zn metal plates were frozen at -10 C, before into the furnace at a temperature ranging from 300 to 420 C for 15 minutes. The ZnO nanostructures were characterized by X-ray diffraction, XRD and field emission scanning electron microscopy( FE-SEM) and X-ray diffraction( XRD) pattern showed the crystal nanostructure of ZnO. FE-SEM images indicated that the nanowires were depended on temperatures. The diameter of ZnO nanowires werevaried from 50 nm to 70 nm and length of several 100 micrometers.
