How it works

Semi-conductor nanocrystals are nanoparticles composed of an inorganic crystalline semi-conductive material and have unique photophysical, photochemical and nonlinear optical properties arising from quantum size effects. A method of making nanocrystals involves adding a chalcogen source to a hot solution of a metal-containing non-organometallic compound in a first ligand solvent and preferably subsequently cooling the resulting mixture to a lower temperature to grow the nanocrystals at lower temperature. The method can involve either one- ligand or two-ligand systems.


  • Synthetic route is shorter and more cost effective
  • Easy to prepare high-quality nanoparticles of various sizes
  • Possible to make two-component nanocrystals
  • Can be formed without the use of acid and at lower temperatures
