| Abstract: | ZnO nanostructures with different morphologies have been synthesized on Si substrate without any catalysts using a simple thermal evaporation method.The effects of oxygen partial pressure on morphology and optical properties of ZnO nanostructures were investigated.The results confirm that the morphology and optical properties of ZnO nanostructures are strongly influenced by oxygen partial pressure,and nanowires,nanobelts and comb-like structures can be obtained atoxygen partial pressure of 25%,10%,and 5%,re... |
