Abstract

ZnO nanorod arrays have been synthesized on silicon wafers by catalyst free thermal vapor deposition with different temperature values. Vertical-aligned ZnO nanostructures were grown at the quite low temperatures by this method. Modification of the method allowed to place silicon substrates in areas with different ratios of concentrations Ar and O2 molecules in the vapor phase. Photoluminescence spectroscopy and electron microscopy studies have shown that morphologies and optical properties of nanorods depends on different ratios of concentrations of the molecules in the vapor phase.
