Comparative Study and Analysis of Structural and Optical Properties of Zinc Oxide Nanoparticles using Neem and Mint Extract prepared by Green synthesis method

Abstract

This work reports the comparative analysis and study of synthesis of Zinc oxide (ZnO) Nanoparticles by using Neem and Mint leaves’ extract by green synthesis method. Green synthesis is a non-toxic, eco-friendly, and low-cost approach to synthesize Nanoparticles. Leaves of Neem and Mint are used for synthesis of ZnO Nanoparticles by boiling at temperature 60°C. The synthesized ZnO NPs (of both extracts) are then characterized separately by using XRD (X-Ray diffraction) confirms the hexagonal (wurtzite) structure of the ZnO nanoparticles with crystalline size 25.51 nanometer and 26.29 nanometer for Neem and Mint respectively, FTIR (Fourier transform infrared spectroscopy) shows the highest peak at 1047cm-1 and 3295cm-1 for Mint and Neem respectively. UV spectroscopy shows the absorption peak for ZnO nanoparticles at 366 nm and 356 nm for Mint and Neem respectively.
