Core-shell hybrid material for ZnO nanorods generation

The aim of our study consisted in obtaining ZnO nanorods using a photonic crystal (PC) structure as substrate. For obtaining of such structures, a PC presenting with electroconductive properties was chosen. Thus, the first step was represented by the synthesis of a copper nanoparticles shell composed by a maximum of seven layers of inorganic particle. This core-shell structure was subsequently used for the generation of ZnO nanorods by electrochemical deposition. The obtained materials were characterized by SEM, dynamic light scattering, UV-Vis, and X-ray powder diffraction analysis.
