| 摘 要： | 以十六烷基三甲基溴化铵(CTAB)为表面活性剂,以氯化锌和氢氧化钠为原料,在低温水热条件下制备出具有纳米片状接枝结构的ZnO微棒。通过扫描电镜(SEM)、X射线衍射(XRD)、透射电镜(TEM)、光致发光(PL)和拉曼光谱(Raman)对产物的形貌、晶体结构和光学性能进行了表征。结果表明,表面活性剂CTAB对产物最终形貌的形成具有重要作用;微棒表面所接枝的薄片为多晶结构;产物光致发光峰是较少见的弱蓝光发射与强红光发射;同时对这种ZnO微棒的生长机理进行了探讨。 |

| Abstract: | ZnO microrods with surface grafting of nanosheets were synthesized by low temperature hydrothermal method using zinc chloride(ZnCl2), sodium hydroxide(NaOH) as reactants and cetyltrimethyl ammonium bromide(CTAB) as surfactant. The morphology, microstructure and optical property of the products were characterized by X-ray diffractometery, scanning electron microscopy, transmission electron microscopy, photoluminescence and Raman spectroscopy. The results show that the appearance of strange shape of ZnO is related to CTAB; the grafted ZnO nanosheets are polycrystalline growing on the surface of ZnO microrods by surface grafting. The product shows a weak blue emission and a strong red emission in PL spectrum. The growth mechanism for the title ZnO microrods is discussed. |
| Keywords: | ZnO surface grafting optical property |
