中文摘要：
利用金属锌片为锌源,采用溶剂热法在锌片表面生长出垂直于表面的直径约为200nm的硫化锌纳米棒阵列。利用X射线衍射（XRD）和扫描电镜（SEM）对不同反应时间制备的锌基硫化锌纳米结构进行表征发现,延长反应时间有助于得到均匀一致的定向生长的纳米棒阵列。利用漫反射紫外可见吸收光谱（UV/Visdiffuse-reflectance spectra）对锌基硫化锌纳米棒阵列在紫外可见光波段的光学吸收性能进行了研究,结果表明合成的结晶性良好的ZnS纳米棒阵列其带边吸收在347nm,对应的禁带宽度为3.47eV。提出了硫化锌纳米棒阵列在形成过程中的化学反应机理。
英文摘要：
ZnS nanorods array on zinc foil was prepared through a solvothermal synthesis route using zinc foil as zinc source and substrate.ZnS nanorods grew along the [001] direction which was perpendicular to the substrate.X-ray diffraction（XRD）and scanning electron microscope（SEM）were used to characterize the as-prepared nanorods array grown under different conditions.UV-Vis diffuse-reflectance spectra of the ZnS nanorods array were also performed by using Shimadzu UV-2550.The results showed well crystalline ZnS nanorods when temperature was 180℃,and reaction time was 8 h.The band-edge absorption of ZnS nanorods array was located at 347 nm,corresponding to the band gap of 3.47 eV.The chemical reaction mechanism of ZnS nanorods formed was discussed.
