Abstract
In this investigation, it was successfully shown that variation of heating media for infused substrates in precursor solution, affects the growth density and size of nanostructured ZnO rods. ZnO rods were prepared by precipitation on a template of cleaned p-type silicon wafer, sputter-coated with a thin layer of gold, infused in prepared precursor solution. The precursor solution consists of 0.01M zinc nitrate hexahydrate (Zn(NO3)2.6H2O) added with equal concentration of stabilizer hexamethylenetetramine, C6H12N4 (HMTA). The set-up was heated in water-bath or dry-oven at a constant low temperature of 80°C. Structural images of the prepared ZnO rods were captured using scanning electron microscope (SEM), its structural phase orientation was characterized by x-ray diffraction (XRD) and its optical property was analyzed from photoluminescence (PL) emission spectra.
