ni doped zno nanorod/glass prepared by chemical bath deposition

In this paper, ni-doped zno nanorods (nrs) with concentrations of (0%, 1%, 2%, and 4%) were successfully grown on glass slides by chemical bath deposition cbd at (85-90) °c. x-ray diffraction (xrd), field emission scanning electron microscopy (fesem), and uv- vis spectrum were performed to characterize the prepared films. the results of the x-ray diffraction measurements of the samples showed that all the prepared films were of a crystalline structure of the hexagonal type with the dominance of growth in the (002) direction and a decrease in the intensity of the peak characteristic with increased ni-doped. the fesem images show the average diameters of zno nrs, ni (1%) nrs, ni (2%) nrs and ni (4%) nrs, there is a clear increase in the rate of the average diameters by increasing the percentage of doping. the band gap of seed layers zno and undoped zno nanorods /glass was found to be 3.25 ev and 3.2 ev respectively. the values of the optical energy gap of ni-doped zno are about (3.12, 3.09, 3) ev with an increase in the rate of doping. the results of the optical and structure measurements also included calculating parameters micro strain (ε), about the ni doped zno (0%, 1%, 2%, and 4%) films for (100), (002), and (101).
