| 摘要: 采用硝酸铋和硫脲为先驱原料，以离子液为反应介质，合成了硫化铋单晶纳米棒。所得产物用X射线粉末衍射、X射线能量色散谱、透射电子显微镜、高分辨电子显微镜、选区电子衍射、扫描电子显微镜、紫外-可见吸收光谱进行了表征。结果表明，在含有乙基硫酸根离子的1-甲基3-乙基咪唑盐的离子液中，160 ℃下回流反应，可以得到结晶良好的硫化铋纳米棒，并对其形成机理进行了探讨。 |

| Abstract: Bismuth sulfide nanorods were synthesized in ionic liquid using bismuth nitrate and thiourea as precursor. The products were characterized by X-ray powder diffraction(XRD), energy dispersive spectroscopy(EDS), transmission electron microscope(TEM), high-resolution electron microscope(HRTEM), selected area electron diffraction(SAED), scanning electron microscope(SEM). The results show that the well crystallized bismuth sulfide nanorods can be obtained at 160 ℃ under refluxing condition. The growth mechanism of nanorods was also discussed. |
