Germanium sulfide (GeS2), also known as germanium disulfide or germanium(IV) sulfide, is a white crystalline solid when pure. Notable as the first germanium compound discovered, during analysis of the mineral argyrodite. Preparation of germanium disulfide is achieved through the reaction of germanium tetrachloride and hydrogen sulfide in a solution of hydrochloric acid.

Applications

Germanium disulfide, like its close relative germanium monosulfide, offers unique optical and electrical properties. Modern research focuses on nanoparticle preparations of these materials, primarily.

  • Semiconductor. Like many closely related compounds, germanium disulfide is a semiconductor of interest in a variety of emerging technologies. Batteries, solar cells, and similar applications may make thorough use of this material at high purities or as nanoparticles.
  • Optics. The natural optical properties of germanium disulfide make it of interest in a number of photo optical applications, with nanoscale particles showing even greater potential.
  • Glass. Germanium disulfide can be used in bulk to produce chalcogenide glasses.
  • Energy storage. As nanoparticles, both germanium sulfide (GeS) and germanium disulfide (GeS2) show exceptional cycling performance in research for lithium-ion batteries, making both potentially valuable materials in any number of energy storage applications.
