Abstract
The magnetic nanoparticle Nickel Oxide(NiO)
hasbeen considered as a promising functional material for
varieties of applications as Smart windows,solar cells
etc.Pure NiO nanoparticles have been synthesized via solgel method.The synthesized precursor was calcined at 400
◦C for 3 hours to obtain pure NiO nanoparticles. FTIR
studies confirms the formation of pure NiO
nanoparticles.Zinc doped NiO nanoparticles are synthesized
by a novel solution phase method employing microwave
irradiation. The aim of this paper is to report the results of
investigations such as XRD,VSM,PL,FTIR & SEM studies
of Pure NiO and Zn doped NiO.VSM studies reveals the
change the magnetic behaviour of both the samples.

Conclusion
Nanoparticles of pure NiO and Zn Doped NiO
nanoparticles has been prepared by sol-gel method and
solvo thermal technique using microwaves. The VSM
studies are undergoing in IIT-MADRAS. We expect some
changes in the magnetic behaviour of NiO and Zn doped
NiO nanoparticles. In future our work can be extended by
doping different transition metal ions with NiO
nanoparticles.
