In this paper, vertically aligned ZnO nanorods arrays were fabricated on different substrates. The substrates are Indium Tin Oxide (ITO) coated glass, polyethylene terephthalate (PET), Silicon (Si), Porous Silicon (PS) and Kapton Tape (KT). Nanorods are fabricated at low temperature by using chemical bath deposition method. The investigation of the effect of substrates on the morphological, elementary composition and structural characteristics of ZnO nanorods has been done. Field emission scanning electron microscopy (FESEM), Energy Dispersive analysis (EDX) and X-ray diffraction (XRD) measurements were used to investigate the morphological, compositional and structural characteristics with hexagonal wurtzite structure of the ZnO nanorods arrays. The average diameter of ZnO nanorods are found to be closely related to the substrates nature. It is concluded that the substrates can effect on the ZnO nanorods growth remarkably and the selective growth of ZnO nanorods is possible through the choice of the substrates. The crystallite size and the lattice constants of the synthesis ZnO nanorods were calculated based on the XRD data. The found results revealed that the increase in the crystallite size is strongly associated with the type of substrate.
