Fabrication of well-aligned ZnCuO/ZnO nanorods

In this thesis, several methods in fabricating well-aligned ZnO nanorods as well as their optical properties will be reported. Firstly, the fabrication of Cu-doped ZnO nanorods via VLS mechanism or electrodeposition method using AAO as templates will be demonstrated. The redshift of the band-gap emission will be illustrated by the measurement of CL spectra and its relation with the doping of Cu will also be discussed. In the second part, AAO membranes are used in the seeded-growth of well-aligned single-crystalline ZnO nanorod arrays as the seeded substrates. The formation of highly-oriented ZnO nanorod arrays will be discussed, hoping to contribute to further research in field-emission or photonic crystal.
