摘要

本篇論文我們研究以硫酸鋅(ZnSO4.Zinc sulfate)去製作生長氧化鋅奈米柱，並且成功生長在銅網的基板上，使用電鍍(electroplating)的方式製作一層晶種層，再以水熱法(hydrothermal method)的方式使硫酸鋅溶液成功生長氧化鋅奈米柱。進一步地，使用硫化納（Na2S•Sodium sulfide）在氧化鋅奈米柱的表面生長一層硫化鋅殼層。為了研究在硫酸鋅生長氧化鋅奈米柱與硫酸鋅生長氧化鋅奈米柱表面硫化鋅殼層之生長時間對於其表面形態樣貌以及其特性，用多種分析例如: 場發射掃描式電子顯微鏡(FESEM)、、光致發光光譜分析儀(PL)、穿透式電子顯微鏡(TEM)測試等等，來進行分析。

This thesis, ZnO/ZnS core/shell structures were fabricated on copper grids and on silicon substrate. With solutions containing ZnO(NO3)2 and ZnSO4. Zinc sulfate was incorporated in the solution to grow ZnO nanorods on copper grids. Firstly, the seed layer was electroplated on the grids or substrates and followed by hydrothermal growth to form ZnO nanorods. Afterwards, ZnS shell was grown on ZnO nanorods’surface in solutions containing Sodium sulfide to form the core shell structure. In order to investigate the characteristics of the structure with various growth time, multiple analyses, such as field-emission scanning electron microscope (FESEM), photoluminescence (PL), transmission electron microscope (TEM) and surface contact angle measurement were performed.
