| 摘 要： | 通过碳热辅助化学气相沉积法, 以Au作为催化剂, 在较低温度(800 益)制备了ZnS纳米线, 其尺寸均匀, 表面光滑, 直径约为40 nm, 具有很大的长径比, 是典型的单晶纤锌矿六方结构. 高分辨透射电镜和选区电子衍射分析表明, 纳米线的生长方向为1100], 与已报道的生长方向不同. 纳米线的生长是由气-液-固(vapor-liquid-solid)机理控制的.

| Abstract: | ZnS nanowires were successfully synthesized through the direct reaction of Zn and S vapor via carbon-assisted chemical evaporation deposition method with Au catalyst. The investigations indicated that the size of ZnS nanowires with a diameter of approximately 40 nm was uniform along the axis of the wire and the surfaces were slick. The ZnS nanowire with a hexagonal wurtzite structure was a typical single crystalline structure. HRTEM and SEAD results demonstrated that the nanowire grew along 1100] direction, which was different from the common direction reported in literatures. The growth of nanowires was controlled by vapor-liquid-solid (VLS) mechanism. |
