Influence of Growth Time on Zinc Oxide Nano Rods Prepared By Dip Coating Method

To read the full article Peer-reviewed Article PDF image


The Dip coating method was used for the preparation of ZnO nano rods and their structural, morphological, optical and photoluminescence properties were taken for study. ZnO seed layer thin films were prepared by dip coating method on well cleaned glass substrates. ZnO seed-coated glass substrates were immersed in aqueous solution of zinc nitrate and hexamethylenetetramine (HMT) at three different growth time of 3, 4 and 5 hours at low temperature of 90°C. 0.02 mol of Zinc nitrate and 0.2 mol of Hexamethylenetetramine (HMT) on 1:10 molar concentration were used for the growth of Zinc oxide nano rods. The growth time influence on the surface morphology of the films was examined. The structure of the ZnO nano rod was studied with X-ray diffraction. The surface morphology was studied with Scanning Electron Microscope. The absorption and transmittance was studied with UVVis spectrophotometer. The excitation studies were examined with photoluminescence spectroscopy. Experimental results have shown that prepared ZnO nano rods by this method have increase in c-axis orientation due to increase in growth time.
