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.Chapter 1 Introduction ............................................................................................ 1 Chapter 2 Experimental Bacground ………………................................................ 5 2.1 Cathodoluminescence(CL) .............................................................................. 5 2.1.1 Introduction of luminescence ..………………………………………… 5 2.1.2 Direct and indirect band gap …………………………………………... 7 2.1.3 Recombination processes ……………………………………………… 10 2.1.4 Cathodoluminescence (CL) …...………………………………………. 13 2.2 Scanning Electron Microscopy (SEM) ......................................................... 15 2.3 Anodic Aluminum Oxide …………………………………………………... 22 2.3.1 Introduction ………………………………………................................. 22 2.3.2 The structure and fabrication of AAO films ......................................... 23 Chapter 3 The fabrication of ZnCuO nanorods ………………………………… 31 3.1 Introduction ………………………………………………………………… 31 3.2 Fabrication of ZnCuO nanorods via VLS mechanism …………………... 34 3.2.1 Experimental details …………………………………………………... 34 3.2.2 Experimental Results ………………………………………………….. 38 3.2.3 Discussion ………………………………………………………………. 44 3.3 Fabrication of ZnCuO nanorods based on AAO templates ……………... 45 3.3.1 Experimental details …………………………………………………... 45 3.3.2 Experimental results and discussion ……………………………………. 48 Chapter 4 Fabrication of well-aligned ZnO nanorods at ow temperature ……… 53 4.1 Introduction …………………………………………………………………… 53 4.2 Experemental details …………………………………………………………. 55 4.3 Results and discussion ………………………………………………………... 58 Chapter 5 Conclusion ……………………………………………………………….. 67en-US氧化鋅奈米柱氧化銅規則排列陽極氧化鋁陰極發光ZnOZnCuOnanorodAAOwell-alignedcathodoluminescence參雜銅之氧化鋅奈米柱之製備/規則排列氧化鋅奈米柱之製備Fabrication of well-aligned ZnCuO/ZnO nanorodsthesis
