Simple solution approach to hollow nanospheres of cubic HgS

摘要

Hollow nanospheres of cubic HgS were fabricated via a simple solution approach. The composite, polymorph, and morphology of as-prepared HgS sample were characterized using XPS, XRD, and TEM. TEM analysis revealed that the hollow nanospheres were relatively uniform, with external diameters of ca. 160-400 nm. TEM analysis at relatively higher resolution revealed that the hollow spheres consisted of small nanoparticles. Based on the experimental results, possible formation mechanism was proposed.
