structural, optical and dielectric studies in zno nanorods by microwave assisted method
Authors
abstract
zno nanorod was prepared by microwave assisted method. the crystal structure of the nano powders were confirmed by x-ray diffraction analysis and the mean particle size was estimated by the scherrer,s formula .the surface morphology of the nano particles were analyzed by using sem . the absorption spectrum of the material in the uv-vis range was recorded .the energy band gap of the material was obtained from the absorption wavelength of the uv-vis spectrum. the short emission wavelength of the material was confirmed by using photoluminescence studies. the effects of frequency on the dielectric behaviour and ac electrical conductivity have been studied.

Nano-structured Zinc oxide is of high potential importance and has wide range of applications. We have made an attempt to investigate the effect of adding Mn 2+ and S 2separately as dopants on the structural, optical, and magnetic properties of nano-structured ZnO. A total of five samples pure and Mn 2+ and S 2added each with two different concentrations viz. 2.5 and 5.0 weight percentages were...

In this study, Pb-filled ZnO nanowires [Pb(core)/ZnO(shell)] were synthesized by a simple and novel one-step vapor transport and condensation method by microwave-assisted decomposition of zinc ferrite. The synthesis was performed using a conventional oven at 1000 W and 5 min of treatment. After synthesis, a spongy white cotton-like material was obtained in the condensation zone of the reaction ...
