N2 - We have demonstrated a simple solvo-chemical and solvo-thermal route to design various nano structures growth of zinc oxide (ZnO). The shapes and morphologies can be easily controlled by using different ambient conditions. We successfully fabricated ZnO nano-wires array on ITO substrate.

This novel synthesis happened under cationic surfactant CTAB in the solution helps to form hierarchical structures of ZnO.
