Growth Structural and Optical Characterization of ZnO

Rod shaped ZnO particles were grown over wood cellulose fibers using a two step process In the first step the formation of ZnO seeds at cellulose fibers surfaces was induced by the alkaline hydrolysis of aqueous Zn II ; in the second step the growth of the ZnO seeds into larger nanoparticles was promoted by the controlled hydrolysis of Zn II −amine complexes In
