摘要

在這篇論文中，我們使用了非真空法製程製作氧化鋅奈米柱的晶種層的成長在各種導電性和非導電性的基板上。氧化鋅奈米顆粒主要是以低溫和低壓環境下水熱法生長。
經由水熱法成長氧化鋅奈米柱，可以觀察到再結晶的情況發生。我們可以監控氧化鋅奈米柱的結晶和品質情況。舉例來說，當我們在製程過程中添加NaOH時，氧化鋅的形狀會有花狀結構出現，也就能區別出氧化鋅奈米柱的不同。
在實驗結果中說明了氧化鋅奈米柱能夠輕易的附著在基板上已成長好的晶種層上。我們再氧化鋅晶種層與氧化鋅奈米柱的製程上採用了不同的實驗參數。為了要觀察不同條件下的成果，利用掃描電子顯微鏡（SEM）進行觀察在不同基板上的氧化鋅奈米柱成長情況。此外，我們在調整水熱環境中的pH值，並觀察氧化鋅奈米柱的生長情形。另外，我也使用X射線繞射分析儀(XRD)和能量分佈質譜儀（EDX）來觀察的氧化鋅奈米柱材料的性質。

In this thesis, we used a non-vacuum method to produce a seed layer of ZnO nanorods which accretes on the various types of conductive and non-conductive substrate. The main ZnO NPs were grown hydrothermally with low temperature and pressure.
Since we grow ZnO NRs by the hydrothermal method, the recrystallization status can be observed. We can monitor the type of crystallization and the quality of the ZnO NRs. For example, when we add the NaOH in the growing environment, the shape the ZnO become flower-like structure, which is distinct from the ZnO NRs.
The experimental results indicate that, ZnO nanorods can adhere easily because of the seed layer on the substrate. We applied different experimental parameters to grow the ZnO seed layer and the ZnO NRs. To examine the experimental condition, ZnO nanorods with various structures can be observed by scanning electron microscope (SEM). In addition, we adjust the pH value in hydrothermal environment to observe the growth of ZnO nanorods. Furthermore, we perform X-ray diffraction (XRD),and energy dispersive X-ray spectroscopy (EDX) to monitor the material properties of the ZnO NRs.
