“…ZRSC exhibits vertically well-arranged growth direction, which are consistent with the XRD results, while ZRCBD exhibits randomly flower like structure in micro-nano size. Vertically well-aligned ZRSC arrays oriented at (002) plane and (0001) direction are in good agreement with the literature [11,21]. Most of these rods have approximately 15 -20° deflection angles from the vertical axis and this result is in good agreement with the literature [21].…”

“…Additionally, it is reported that 2 theta degree of (002) peak for ZnO hydrophobic film growth by using CBD is identified between 50° -55° with highly intensity [19]. However, 2 theta degrees of (002) peaks for ZRCBD and ZRSC which is identified approximately at 35°, is in good agreement with hydrothermal studies [11,21].…”

In this study, Zinc Oxide (ZnO) seed layers were prepared on Indium Tin Oxide (ITO) substrates by using Chemical Bath Deposition (CBD) method and Sol-gel Spin Coating (SC) method. ZnO micro-nanorod arrays were grown on ZnO seed layers by using Hydrothermal Synthesis method. Seed layer effects of structural and optical properties of ZnO arrays were characterized. X-ray diffractometer (XRD), Scanning Electron Microscopy (SEM) and Ultraviolet Visible (UV-Vis) Spectrometer were used for analyses. ZnO micro-nanorod arrays consisted of a single crystalline wurtzite ZnO structure for each seed layer. Besides, ZnO rod arrays were grown smoothly and vertically on SC seed layer, while ZnO rod arrays were grown randomly and flower like structures on CBD seed layer. The optical absorbance peaks found at 422 nm wavelength in the visible region for both ZnO arrays. Optical bandgap values were determined by using UV-Vis measurements at 3.12 and 3.15 eV for ZnO micro-nanorod arrays on CBD seed layer and for ZnO micro-nanorod arrays on SC-seed layer respectively.
