Figure 1From: Solvothermal synthesis, growth mechanism, and photoluminescence property of sub-micrometer PbS anisotropic structuresTEM and SEM images of the fishbone-shaped PbS crystals. Obtained via solvothermal route without surfactants at 165°C for 12 h. (a) Dendrites, (b) three-dimensional dendritic structures, (c) hierarchical dendritic structures, and (d) incomplete dendrites.Back to article page
