摘要: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 wereprepared by dip coating method on well cleaned glass substrates. ZnO seed-coated glass substrates were immersed inaqueous solution of zinc nitrate and hexamethylenetetramine (HMT) at three different growth time of 3, 4 and 5 hoursat low temperature of 90°C. 0.02 mol of Zinc nitrate and 0.2 mol of Hexamethylenetetramine (HMT) on 1:10 molarconcentration were used for the growth of Zinc oxide nano rods. The growth time influence on the surface morphologyof the films was examined. The structure of the ZnO nano rod was studied with X-ray diffraction. The surfacemorphology was studied with Scanning Electron Microscope. The absorption and transmittance was studied with UVVisspectrophotometer. The excitation studies were examined with photoluminescence spectroscopy. Experimentalresults have shown that prepared ZnO nano rods by this method have increase in c-axis orientation due to increase ingrowth time.
