采用AOT/正庚烷/水微乳液法制备了CdS-Ag_2S核壳结构纳米粒子及复合纳米粒子。我们系统地研究了不同的微乳液混合方法来制备核壳纳米颗粒。使用了四种方法。虽然所有的方法产生纳米颗粒和纳米复合材料，只有两个，即后核和部分微乳液方法已显示出核和壳的形成和增强的稳定性和球形的纳米颗粒的前景。这些核和壳纳米粒子和纳米复合材料已使用TEM，EDAX，光致发光和紫外-可见分光光度计技术进行了表征。结果和可能的机制，通过所有四种方法形成的纳米粒子进行了讨论。(C)2003 Elsevier B. V.保留所有权利。
An attempt has been made to synthesize CdS-Ag2S core-shell and composite nanoparticles using AOT/n-heptane/water microemulsion technique. We have systematically studied the different microemulsion mixing methods to prepare core and shell nanoparticles. Four methods have been used. Whilst all methods produced nanoparticles and nanocomposites, only two, i.e. the post-core and partial microemulsion methods have shown promise for core and shell formation and enhanced stability and sphericity of the nanoparticles. These core and shell nanoparticles and nanocomposites have been characterized using TEM, EDAX, photoluminescence and UV-Vis spectrophotometer techniques. Results and possible mechanism of formation of nanoparticles via all four methods have been discussed. (C) 2003 Elsevier B.V. All rights reserved.
