Gallium selenide

Gallium selenide, also known as gallium(II) selenide or gallium monoselenide, is a brown compound composed of gallium and selenium. Currently, much of the interest in gallium selenide is focused on nanoparticles of high purity and its potential as an optical material, especially at nanoparticle scales.

Applications

While it shows considerable potential as a photo-conductor, nonlinear optics material, and infrared conversion material, it continues to be of limited value commercially due to the difficulty of exploiting its properties on a large scale.

  • Photoconductor. Most academic and commercial interest in gallium selenide focuses on its properties as a photoconductor, i.e. its increased electrical conductivity in response to electromagnetic radiation. While successful applications have been developed, practical limitations exist due to the difficulty of producing single crystals of gallium selenide or cutting those crystals without unexpected breaks along cleavage lines. Doping with indium shows promise in resolving the latter problem, while advances in nanoscience may resolve the former.  
  • Nonlinear optics. Gallium selenide is particularly interesting as a potential second harmonic generation crystal in nonlinear optics. It could be used to convert electromagnetic radiation from one wavelength to another, in particular converting far-infrared radiation.
