摘要：
Novel hierarchical HgS dendrites were synthesized in high yield by hydrothermal treatment of a mercury (II)-thiourea complex. The individual HgS dendrite consists of a long central trunk with secondary and tertiary sharp branches, which preferentially grow parallel to the (001) plane. The possible growth process is proposed by arresting the growth at a series of intermediate morphology stages during the shape evolution of HgS dendrites based on SEM observations.
