•All the nanostructures of ZnO were preferentially grown as nanorods along [0002] direction (c-axis) of the hexagonal wurtzite.•The strain values are negative which indicates that the ZnO nanorods are grown under compressive strain.•The ZnO on the seeded substrate was better and the nanorods were better vertically aligned than the growth of ZnO on non-seeded substrate.
The synthesis of ZnO nanorods on transparent conducting oxides, Al doped ZnO seed layer on glass substrate (AZO) and indium tin oxide substrate (ITO) by using zinc nitrate hexahydrate (Zn (NO3)2·6H2O) and hexamethylenetetramine (HMT, (CH2)6N4 as raw materials is presented. The ZnO seed layer was fabricated by depositing an Al-doped ZnO thin film on glass substrate by sputtering. The effect of seeding on (AZO) and (ITO) substrate by using the wet chemical route growth of ZnO nanorods was investigated. The synthesized nanostructures of ZnO were characterized by X-ray diffraction (XRD), UV–vis absorption spectroscopy, scanning electron microscopy (SEM) and high-resolution transmission electron microscopy (HRTEM). The results indicate that all the nanostructures of ZnO are preferentially grown as nanorods along [0002] direction (c-axis) of the hexagonal wurtzite structure and the nanorods which are grown on annealed seeded substrate are well shaped hexagonal faceted unlike those formed on non-seeded substrate. However we have observed that when we were increased the aluminum doping on the seed layer the ZnO growth was as nanoplatelets.
