Shape Control of PbS Crystals under Microwave Irradiation

The growth of PbS crystal was kinetically controllable by adjusting the concentration of the anion surfactant sodium dodecylbenzenesulfonate (SDBS) and the acidity of the solution under microwave irradiation. SDBS favored stacking in the (111) plane but blocked that along the  zone axis. Adjusting the ratio of SDBS and HNO<sub>3</sub> led to the formation of hexapod, concave, and truncated octahedron PbS.
