Abstract:
ABSTRACT ZnO plays an important role in many semiconductors technological aspects. In the present work zinc oxide nanorods were prepared by chemical method , using ( Zn (NO₃)₂.6H₂O) and (NaOH) at 70ºC , 80ºC . A variety of techniques like X-ray diffraction (XRD),Scanning Electron Microscopy (SEM) and UV-Vis absorption spectroscopy were used to carry out structural and spectroscopic characterizations of the nanorods . X-ray diffraction revealed the wurtzite structure of ZnO . Scanning electron microscopy (SEM) results illustrated that all nanostructures are nanorods and the diameter of (30–50 nm) to length (500nm – 1 μm). It has been observed that the diameter and length of nanorods were changed with the change in temperature of interaction . The UV-VIS absorption spectra showed rade shift and blue shift in wavelength corresponding to bulk. Band gap energy of ZnOnanoparticles were determined from UV reflectance spectra and confirm quantum confinement. Keywords:ZnOnanorods,chemical method,changing growthtemperature.
