Structural and Optical Properties of ZnO Nanorods Thin Films Prepared by Hydrothermal Method and Effect of growth time

Ahmed Saud Abed


This paper describes, Synthesis of zinc oxide nanorods (ZnO NRs) by hydrothermal method at different growth time. The structural and morphological properties were characterized by X-ray diffraction (XRD), Energy Dispersive X-Ray (EDX) and Field Emission Scanning Electron Microscope (FE-SEM). The ZnO nanorods are obvious hexangular wurtzite structure and preferentially oriented along the c-axis (002) and growth vertically to the substrates. The optical properties were studied, from UV-Visible spectrophotometer and Photoluminescence (PL), the optical band gap energy of all samples ZnO nanorods prepared (S1, S2 and S3) was calculated to be (3.425 eV, 3.4 eV, 3.425 eV) respectively. Also, studied effect of growth time on ZnO nanorods.
