— In the area of synthesis of nano materials, research and development are mainly oriented to control the shape, size, structure and compositions of nano materials. Each of these factors is a key factor in determining the properties of nano materials that lead to different technological applications. Nano zinc oxide is a multifunctional material with its unique physical and chemical properties such as high chemical stability, high electrochemical coupling coefficient, broad range of radiation absorption and high photo-stability. In this research work a very simple but effective technique has been developed to synthesize zinc oxide (ZnO) nano particles using zinc nitrate and potassium hydroxide (KOH) in aqueous solution. The precipitated amalgam has been dried, calcined, grinded and characterized by UV-vis spectroscopy, transmission electron microscopy (TEM) and dynamic light scattering (DLS). The ZnO nanoparticles displayed characteristic surface plasmon resonance peak at around 372 nm. Particles-size distribution by dynamic light scattering technique showed that the particles were found in the range of 15-45 nanometer (nm) for the purpose of advance applications.
