Facile Synthesis and Characterization of Flower-Like PbS Microstructure via a Solvothermal Route

摘要

PbS flowers were successfully synthesized by a simple solvothermal route. X-ray diffraction (XRD), scanning electron microscopy (SEM) showed that the as-prepared PbS microcrystals had a cubic structure and exhibited a beautiful six-petal flower-shaped morphology. The acetic acid and the ratios between lead acetate and element sulfur play key role in controlling the flower-like PbS microstructure. Then, based on a series of reference experiments, a possible formation mechanism was discussed. Furthermore, the optical and fluorescence properties were also investigated.
