Abstract

Nanotechnology has come to mean a range of highly promising disciplines in science and
technology. Metal oxide Nanoparticles had been used in recent studies due to its large bandwidth and
high binding energy and it has potential applications like antibacterial, antifungal, anti-diabetic, antiinflammatory,
wound healing, anti-oxidant and optic properties. The usages of nanomaterials are
enormous as energy storage devices such as fuel cells, detection of threads in defence, navy, drug
delivery and water purification. Green synthesis of Nanoparticles has received a lot of attention and
close scrutiny of scientists and researchers. Leaf extract of Azadirachta Indica contains phytochemicals
and enzymes which take part in the conversion of metal compounds into Nanoparticles. Pure zinc oxide
and Manganese oxide is prepared and doped with Azadirachta Indica to analyse its general and optical
properties. We have attempted to prepare pure ZnO and MnO Nanoparticles also both were doped with
neem at 5:1 ratio by using solvothermal method.
