Investigation on the Deposition of the Nd doped ZnO Thin film and Their Structural and Optical Properties

Zinc oxide (ZnO) and Neodymium-doped zinc oxide thin films were deposited onto the glasssubstrates at 4000C by the spray pyrolysis method for various doping concentrations ofNeodymium (Nd) in the spray solution. The modification on the structural and opticalproperties for various neodymium incorporation levels was investigated. The growthorientation of the ZnO and Nd doped ZnO thin films were investigated by XRD patterns. Allthe deposited films are polycrystalline in nature and the films exhibit hexagonal wurzitestructure with c-axis orientation along (002) direction. The grain sizes varied from 23-46 nmwith various concentrations of Nd. Morphological studies and composition of the films wereperformed by SEM and EDX analyses, respectively. Formation of ring shaped patterns areobserved on the surface of the Nd doped ZnO thin film. This is confirmed with EDX spectrum.PL spectra showed that Nd doped ZnO thin film exhibit a low density of native defects. Nddoped ZnO thin films were obtained for the same deposition parameters such as spray time,spray interval, compressed air pressure and distance between spray nozzle and substratewere kept constantSelection and Peer-review under responsibility of [Conference CommitteeMembers of Recent Advances In Nano Science and Technology 2015.]
