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
