Abstract

ABSTRACT
Through the utilization of Mangifera indica extract, we have accomplished a successful and environmentally friendly green synthesis of zinc oxide nanoparticles (ZnO-NPs). These nanoparticles were precipitated with the aid of an aqueous extract from M. indica and subsequently subjected to a characterization process at a temperature of 450°C. In the ultraviolet-visible spectrum, the aqueous mixture of ZnO-NPs displayed a notable peak absorption wavelength range at 374 nm, accompanied by a calculated band gap of 3.32 eV, signifying substantial progress in their development. The FTIR analysis revealed an absorption peak at 456 cm-1 , corresponding to Zn-O stretching, along with an O-H bond intensity at 3425 cm-1 . Additionally, SEM imaging provided visual evidence of irregularly distributed spherical-shaped particles, with an average size measuring approximately 86.7 nm. Comprehensive analysis further affirmed the successful formation of zinc oxide, highlighting nearly equal atomic ratios between Zn and O elements, indicating a 1:1 ratio. This investigation underscores the potential of water extract derived from Mangifera indica as a promising and eco-friendly alternative for synthesizing nanoparticles, such as ZnO-NPs.
