在十六烷基三甲基溴化铵（CTAB，CH 3（CH 2）（15）N+（CH 3）（3）Br-）表面活性剂存在下，采用自组装法在室温下合成了片状ZnO/表面活性剂有序层状纳米复合材料。在这项研究中所描述的程序是有吸引力的，因为它给出了高产量的有序层状纳米复合材料与片状结构。XRD结果表明，形成了两层间距约为100 μ m的层状结构。18.56 A.利用SEM和FT-IR对ZnO/CTAB纳米复合材料进行了表征。ZnO/CTAB有序层状纳米复合材料具有室温光致发光（RTPL）特性。由此推测，ZnO/CTAB层状纳米复合材料的RTPL可能是由ZnO与表面活性剂之间的界面效应引起的。(c)2006年由Elsevier B.

Flake-like ZnO/surfactant ordered layered nanocomposite has been synthesized by self-assembly at room temperature with the presence of cetyltrimethylammonium bromide (CTAB, CH3(CH2)(15)N+(CH3)(3)Br-) surfactant. The procedure described in this study is attractive since it gives high yields of ordered layered nanocomposite with flake-like architecture. XRD results showed the formation of a layered structure with two layered spacings ca. 18.56 A. SEM and FT-IR spectroscopy were used to further characterize ZnO/CTAB nanolayered composite. The ZnO/CTAB-ordered layered nanocomposite exhibits the room temperature photoluminescence (RTPL) characteristics. It is inferred that the RTPL of Zn0/CTAB-layered nanocomposite might be induced by the interfacial effect between the ZnO and the surfactant. (c) 2006 Published by Elsevier B.V.
