本研究利用陽極處理所得之陽極氧化鋁(Anodic Aluminum Oxide, AAO)作為模板，以真空壓鑄之方法製備鉛奈米線陣列，接著透過硫化處理獲得硫化鉛奈米線。利用不同種類之電解液包含硫酸、草酸及磷酸，製備之陽極氧化鋁孔徑可控制於30-300 nm之間，而奈米線之線徑大小取決於陽極氧化鋁模板之奈米孔徑，分別製備線徑約為30、100及300 nm不同尺寸之奈米線進行後續分析。為了探討生長條件對鉛硫化程度之影響，將硫化溫度及時間設為實驗參數。利用場發射掃描式電子顯微鏡觀察陽極氧化鋁模板及奈米線之表面微觀形貌。透過能量色散X射線光譜分析不同硫化條件之奈米線成份比，使用X光繞射儀及穿透式電子顯微鏡鑑定其晶體結構。利用紫外光-可見光/近紅外光分析儀得到奈米線之吸收光譜，結果顯示，由於奈米線受到量子侷限效應，其吸收光譜會隨著線徑增減而位移，故可透過控制硫化鉛奈米線之線徑獲得不同波段之吸收。

In this study, lead sulfide(PbS) nanowires were fabricated with anodic aluminum oxide(AAO) by using vacuum injection molding and sulfurization processes. Using different types of electrolytes including sulfuric acid, oxalic acid and phosphoric acid, the varied anodic aluminum oxide(AAO) pore size can be controlled between 30 nm – 300 nm. The diameter of nanowires depends on the pore size of anodic aluminum oxide(AAO) template, and the nanowires with diameters of approximately 30, 100 and 300 nm were prepared for analyses. In order to investigate the effect of growth conditions for the fabrication of lead sulfide, the correlation between control variables (sulfurizing temperature and time) and the properties of lead sulfide was established. The morphology of AAO templates and nanowires were observed by Field-Emission Scanning Electron Microscope(FE-SEM). The compositions of the nanowires with different sulfurization conditions were analyzed by Energy Dispersive X-ray spectroscopy(EDS) and the crystal structure was identified by X-ray diffractometer(XRD) and Transmission Electron Microscopy(TEM). Furthermore, the absorption spectrum of lead sulfide nanowires were obtained by UV-VIS/NIR spectrophotometer. The results show that absorption peak shift as nanowires diameter change due to the quantum confinement effect.
