The Electrodeposition of Zinc Oxide Two-Dimensional Nanomesh and Three-Dimensional Inverse Opal Complex Connected Structures

The fabrication of the periodic ordered structures with complex shapes or heterostructures are important for many potential applications. In this paper, zinc oxide two-dimensional (2D) nanomesh and three-dimensional (3D) inverse opal complex connected structures were fabricated by the electrochemical deposition method. 2D ZnO nanosheets or sheet-like porous structures standing on the 3D ZnO inverse opals were synthesized. Two different methods: the co-deposition method and the two-step deposition method were employed for the preparation of the complex structures. The deposition process of complex structures is discussed. The photonic band gap of the complex macroporous structure was calculated using the Translight software and characterized by the microregion reflection and transmission spectra. The exciton luminescence of ZnO can be inhibited by the inverse opal structure when the photonic band gap superposes with the luminescent band.
