Structural and Optical Investigation of ZnO Nanopowders Synthesized from Zinc Chloride and Zinc Nitrate

摘要

ZnO Nanopowders were synthesized from Zinc Chloride and Zinc Nitrate by Co-precipitation Method. The synthesized ZnO nanopowders were further characterized using X Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR) Spectroscopy. The Structure, Morphology and Optical properties were investigated for each precursor. XRD patterns indicate hexagonal wurtzite structure with high crystallinity. SEM images revealed the morphology of the ZnO Particles. The optical characterizations of ZnO nanoparticles have been carried out using FTIR Spectroscopy. The spectrum shows the characteristic absorption peaks of Zn-O are nearer to 390 cm^-1 and also authenticates presence of ZnO. From the analyses of results, it is very clear that precursors used in the present study have played a vital role in surface morphology, structural and optical properties of ZnO nanoparticles.
