| 摘要: 通过调节葡萄糖浓度，采用十六烷基三甲基溴化铵(CTAB)辅助水热法选择合成了Se和Se@C纳米棒，并用扫描电镜(SEM)、透射电镜(TEM)、粉末X射线衍射(XRD)和X射线能谱分析(EDS)对产物进行了表征。结果表明，产物Se纳米棒直径200～300 nm，长达数微米；Se@C纳米棒长达数微米，内核直径200～00 nm，壳厚约30 nm。初步探讨了Se和Se@C纳米棒的生长机制。 |

| Abstract: Se and Se@C nanorods were fabricated by adjusting concentration of glucose in the presence of cetyltrimethylammonium bromide(CTAB) under hydrothermal conditions. The as-synthesized Se and Se@C nanorods were characterized by SEM, TEM, XRD and EDS. The results show that products are Se nanorods with diameters ranging from 200 to 300 nm, lengths of several tens microns, and Se@C nanorods with lengths of several tens microns, core about 200～300 nm in diameter, a surrounding sheath about 30 nm in thickness. The formation process of Se and Se@C nanorods was proposed. |
