History of Quantum Dots


QDs have been in use since the early 1980’s, the expansion of this technology has been hindered as the currently employed synthesis method is very complex, carried out at high temperatures and under an inert atmosphere of argon, time dependent and therefore difficult to control. It does not allow for the process to be easily scaled up. In addition the current QDs are cadmium based, a toxic element that further limits the use of these dots. Cadmium is banned for use in consumer products in the EU and Japan and an increasing number of countries across the globe are moving to enact similar regulations.

QTG owns the exclusive license with rights to sub-license university based IP that will allow for QDs to be synthesized in an easy, scalable and environmentally friendly manner. This patented synthesis process is carried out at room temperature and normal environmental conditions, is not time dependent and can be run in volumes from milliliters to liter quantities without the need for any significant process modifications. Furthermore, the toxicity will be eliminated by replacing the Cd with non toxic Zn as the core of the dots. The ability to synthesize non-toxic ZnQDs in large quantities with a consistent quality to allow for these very unique nanoparticles to be applied to a host of technologies ranging from LCDs, LED, solar panels, anti counterfeiting applications to diagnostics, to name a few.

QDs, like thin films in the 1980’s, are expected to revolutionize and advance the application of current and future technologies across a wide range of industries.
