Chalcogenide Materials

A template-free and surfactant-free hydrothermal method has been successfully developed to fabricate hierarchically dendritic metal sulfides ( PbS and CdS ). It has been found that the reaction temperature play important roles in the formation of well-defined sulfide dendritic nanostructures. A possible mechanism for the formation of present dendrites was proposed. The as-obtained transition-metal sulfide dendritic nanostructures may bring wide applications in optics, electricity, gas sensors, and other related fields. The synthetic route present in this work provides a new principle for the designing synthesis of dendritic metal sulfide nanomaterials and can be regarded as a general way to fabricate other metal chalcogenide materials.
