On the structural and optical properties of nano-ZnO and its morphologies

Since, variety of morphologies is reported for nano zinc oxide (ZnO), few of those which are useful for applications, are analyzed here with reference to optical properties. Nanoparticles, nanorods and chunk-shaped nanostructures are grown and these growth mechanisms were discussed in detail. The chemical compositions and vibration modes were analyzed by FTIR. UV-vis and PL characterization were also analyzed. The Verdet constants, obtained from the Faraday rotation of polarized light for all synthesized nanostructures, show distinct behavior of the above ZnO nanostructures.
