Structural and Optical Properties of ZnO Nano Particles Synthesised by Mixture of Fuel Approach in Solution Chemical Combustion

Abstract

Zinc oxide has been used for many applications, for example optoelectronic devices, ceramics, catalysts, pigments, varistors and many other important applications. In this study, ZnO nanoparticles were synthesized by mixture of fuel approach in solution chemical combustion method. Mixtures of Urea and Zinc salts were mixed at room temperature resulting in spontaneous ignition because these are hypergolic materials resulting in production of ZnO nanopowder. The crystal structure and size of the synthesized powder were determined by X- ray diffractometer (XRD), which revealed that the synthesized ZnO nanopowder has the pure wurtzite structure having average crystallite size of 30nm. Morphological studies were carried out by scanning electron microscopy (SEM), Energy Dispersive X-ray analysis (EDAX) was carried out by Scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDAX), Optical studies were examined by FT-IR and UV-Visible absorption spectrum and the particle size was estimated from Nanoparticle size analyzer.
