摘要

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.
