Green synthesis of ZnO nanoparticles using abrus precatorius seeds extract and their characterization

Vishwakarma, Kavita (2013) Green synthesis of ZnO nanoparticles using abrus precatorius seeds extract and their characterization. MSc thesis.



In modern science Nanotechnology is a ablaze field for the researchers.Nanoparticles having a size of 1-100 nm in one dimension, is used significantly concerning medical chemistry, atomic physics, and all other known fields. Nanoparticles are used immensely due to its small size, orientation, physical properties,which are reportedly shown to change the performance of any other material which is in contact with these tiny particles. These particles can be prepared easily by different chemical, physical, and biological approaches. But the biological approach is the most emerging approach of preparation, because, this method is easier than the other methods, ecofriendly and less time consuming. The semiconductor ZnO has gained substantial interest in the research community in part because of its large exciton binding energy 60 meV which could lead to lasing action based on exciton recombination even above room temperature. The Green synthesis was done by using the aqueous solution of Abrus precatorius seeds extract and zinc acetate. A fixed ratio of plant extract to metal ion was prepared and the color change was observed which proved the formation of nanoparticles. The nanoparticles were characterized by UV-vis Spectrophotometer, FTIR, DLS, Zeta Analysis, XRD, and SEM. The particles synthesized were of the size ranging from 90-500 nm.
