Abstract: Zinc oxide (ZnO) nanostructures have been grown on glass and silicon substrate by microwave assisted wet-chemical (MAWC) method and thermal evaporation using TGA. The effect of different preparative parameters on the growth of ZnO nanostructures has been studied. The synthesized nanostructures are characterized using UV-Vis spectroscopy, particle size analyzer, XRD, SEM, and EDX. ZnO nanostructures, i.e. nanorods (NRs) obtained using evaporation method are of 200-250 nm in diameter and nanopolypods (NPPs) with pod diameter in the range 150-200 nm and pod length in the range 700-800 nm, whereas from MAWC method, NRs produced are 100-150 nm in diameter and NPPs with pod diameter in the range 150-200 nm and 1.5-2 µm of pod length. XRD studies show that the prepared samples are nanocrystalline in nature with hexagonal wurtzite phase and highly oriented along (002) direction.
