چکیده
In the recent era zinc oxide nanoparticles attracted the researchers due to their unique properties and applications in optoelectronic devices. Zinc oxide nanoparticles are the semiconductor materials having band gap energy 3.37 eV and very large excitation binding energy (60meV) at room temperature. Also it is non-toxic, environmental friendly and transparent to visible range of spectrum. In the present investigation Zinc oxide nanoparticles were synthesized by sol gel method using zinc acetate and sodium hydroxide as precursors and de ionized (DI) water as solvent. The structure and morphology of prepared zinc oxide nanoparticles was studied using X-ray diffraction (XRD) spectroscopy and Scanning Electron Microscopy (SEM). UV visible spectrum shows the transparency of nanoparticles over entire visible range. The FTIR analysis confirms the formation of zinc oxide nanoparticles.
