Abstract: In this paper, a simple green route combustion method of synthesis was adopted for the synthesis of Zinc oxide nano particles using Euphorbia milli latex as fuel. As prepared product was characterized by Powder X Ray Diffractometer (PXRD), Fourier Transform Infra-Red spectroscopy (FTIR), UV-Visible spectroscopy, Rietveld refinement, Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS) and Transmission Electron Microscopy (TEM). The concentration of plant extract plays an important role in controlling the size of the particle and its morphology. PXRD graphs showed that the particles were well crystallised. The average particle size was calculated using Scherrer equation and advanced WH plots. The average particle size is around 50nm. This result was also supported by SEM and TEM analysis. FTIR shows the characteristic peak of ZnO at 435 cm-1. SEM and TEM micro graphs show that the particles are spherical in nature. EDS of SEM analysis confirmed that the elements are only Zn and O. No other impurity elements were found in the sample. Crystal parameters were determined using Rietveld refinement. From UV-Visible spectra band gap energy was found to be 3.44 eV. This method is fast, eco friendly and convenient for the synthesis of ZnO nano particles (NPs).
