硫化鋅奈米線由於其優異之光電性質，目前已成為奈米材料領域最受矚目的研究之ㄧ。然而，製備大規模且均ㄧ性佳之硫化鋅奈米線陣列仍是ㄧ大挑戰。因此本研究欲利用水熱法並以孔洞型態均一之多孔性陽極氧化鋁作為模板，合成硫化鋅一微奈米線陣列，探討其合成機制與光電特性。
本研究所使用之前驅物溶液分別為氯化鋅及硫脲之混合溶液(後段簡本實驗分別以三組不同之前驅物溶液製備硫化鋅粉末及其奈米線陣列。三種稱為A溶液)、氯化鋅及硫代乙醯胺之混合溶液(後段簡稱為B溶液)、含水醋酸鋅及硫脲之混合溶液(後段簡稱為C溶液)。此外，硫化鋅粉末及其奈米線陣列之成長基材則分別為玻璃與多孔性陽極氧化鋁模板。
實驗結果顯示此三組前驅物溶液皆可製得硫化鋅粉末，但僅以C溶液可成功製得硫化鋅奈米線陣列。就硫化鋅粉末之型態而言，A溶液所製得之粉末為空心微球體，另外兩種溶液所製備者則是實心微球體。此外，以B溶液所製得之實心微球體由尺寸約10nm之球狀奈米顆粒所構成，而C溶液所製得者則由約40至50nm之球狀、棒狀奈米顆粒所構成。就硫化鋅奈米線之型態而言，其直徑約100nm且符合模板孔洞尺寸。
本研究可歸納出不同前驅物作用於硫化鋅粉末之效應，亦可得知其奈米線陣列之形成機制。

Zinc sulfide nanowires have attracted great attention because of the specific optical and electronic properties. The preparation of large-scale and homogeneous zinc sulfide nanowire arrays is still a challenge.
In this research, three types of precursor solution were used for the synthesis of ZnS powder and its nanowire arrays. The three solutions include zinc chloride and thiourea(noted as solution A ), zinc chloride and thioacetamide(noted as solution B), zinc acetate dihydrate and thioacetamide(noted as solution C). In addition, the growth substrate of ZnS powder and nanowire arrays are glass and porous alumina membrane, respectively.
Experimental results indicate that ZnS powder can be synthesized with all types of precursor solution. However, ZnS nanowire arrays can be synthesized with only solution C. The morphology of the powder prepared with solution A is hollow microspheres, but that of the powders prepared with other solutions is both solid microspheres. Moreover, the solid microspheres prepared with solution B consist of the spherical nanopartricles with size is about 10nm, and the product prepared with solution C consist of the spherical and rod-like nanoparticles whose size is about 40-50 nm. For the morphology of the ZnS nanowires, their diameter is about 100nm and that fit the pore size of the templates.
From our research, we conclude the effect of different precursors which works on the ZnS powders and the mechanism of the formation of ZnS nanowire arrays.
