Syzygium cumini Linn., Zinc Oxide Nanoparticles, ZnO NPs, XRD, FTIR and SEM.
Zinc oxide nanoparticles (ZnO) were synthesized using aqueous leaf extract of Syzygium cumini Linn (Jambolana). Due to having no toxic effects on an environment green synthesis has become one of the most important methods for the synthesis of particles at nanoscale, therefore plant extract was used for the synthesis of biogenic ZnO Nps. The UV-Vis spectrum was used as a confirmational tool for the prepared particles either were in nano scale range or not. Prepared green nanoparticles were further processed for the XRD and SEM analysis so that the exact size and shape of experimental particles were calculated. The presence of the active compounds or functional groups were further calculated using FTIR analysis. Change in color of the mixture (pale yellow to whitish) was the first confirmation of ZnO particles while UV vis analysis presented a sharp peak at 378 nm which confirmed the synthesized particles were in nanoscale. The hexagonal wurtzite structure of ZnO nanoparticles was confirmed through XRD analysis which give distinct peaks at 2θ position. The average size calculated was around 70 nm with irregular shape of particles.
