3D PbS dendritic nanostructures (see Figure) have been fabricated by a facile hydrothermal method in the presence of N ‐cetyl‐ N , N , N ‐trimethyl‐ammonium bromide (CTAB). Both CTAB and thiourea play important roles in the formation of well‐defined PbS dendrites. X‐ray diffraction, electron diffraction, and high‐resolution transmission electron microscopy results show that the PbS nanostructure is a 3D dendrite of a single crystal.
