| 摘 要： | 以一种实验室自合成的双子季铵盐为表面活性剂,采用水热法,通过调节pH值,制备出由Bi2WO6纳米片自组装而成的不同片状团簇微球。研究了不同Bi2WO6片状团簇微球的物相结构、成分、晶体形貌和光致发光特性,探讨了其可能的生长机理。结果表明,在这种多季胺阳离子作用下,pH值对Bi2WO6片状团簇微球的物相、形貌和光致发光性能有明显的影响,随着pH值的增大,Bi2WO6片状团簇微球在(131)晶面处呈现明显的择优取向生长,在pH=5时,Bi2WO6微球可达到最大的发光强度。

| Abstract: | By using a Gemini quaternary ammonium as surfactant synthesized in laboratory and adjusting the different pH values, in this study, using the hydrothermal method, the different sheet-like cluster microspheres was self-assembled by Bi2WO6 nano-sheets. This study analyzed and characterized the effect of pH value on synthesis of Bi2WO6 sheet-like cluster microspheres, phase structure, composition, crystal morphology and photoluminescence properties, and explore its possible growth mechanism. The results show that different pH values caused a significant impact in Bi2WO6 sheet-like cluster microspheres phase structure, morphology and photoluminescence properties, when A multi-quaternary ammonium cationic dispersant as structure directing agents in the growth stage of Bi2WO6 Microspheres. With the increasing of pH value, sheet- like clusters Bi2WO6 microspheres showed obvious trend growth in the (131) direction, when pH=5, Bi2WO6 microspheres can reach a maximum luminous intensity. |
