Optical and Structural Investigation of Mg2+ doped ZnO Nanoparticles using Gymnema sylvestre and Mangifera indica Leaves Extracts

Abstract

In green nanotechnology, plant is used for the synthesis of nanoparticles which are gaining considerable interest among researchers as an eco-friendly alternative to conventional physical and chemical methods, as this approach eliminates the use of toxic chemicals. The present study describes the synthesis of Mg2+ (magnesium) doped zinc oxide (ZnO) nanoparticles (NPs) M1 using leaves extract of Gymnema sylvestre (G. sylvestre) belonging to Asclepiadaceae family and M2 using Mangifera indica (M. indica) belonging to Anacardiaceae family as reducing as well as capping agents. The obtained Mg2+ doped ZnO NPs (M1 and M2) were characterized by X-ray diffraction (XRD) studies, field emission scanning electron microscopy (FESEM), elemental analysis (EDAX), Fourier transform infrared spectroscopy (FTIR), UV-vis spectroscopy and photoluminescence (PL) spectra.
