PhosphorDots non toxic quantum dots, with UV illumination

This demo shows PhosphorDots being added to water on a UV light table, showing how they are transparent but light up brightly. Sun Innovations’ PhosphorDots are a type of non-toxic quantum dot for medical research, optoelectronics, solar, and other applications. PhosphorDots solve limitations of standard quantum dots including toxicity, ease of functionalization without ligand exchange, lifetime, and the ability to have aqueous dispersions. Current quantum dots require shells to prevent them from oxidization, increasing the manufacturing cost. Also, doubts usually linger that the shell won’t last and oxidization and/or the release of toxins will occur. Our PhosphorDots are non-toxic oxides, so they are inherently more stable than traditional quantum dots, while they last orders of magnitude longer than organic dyes. By eliminating the requirement for organic capping and an inorganic shell, there are less prospective points of failure in the material due to thermal, chemical, or other variables. Because our materials are more stable and easier to manufacture, they help slash the cost of using quantum dots, and make using them in new applications such as digital signage and solar an option. According to BCC research, the market for quantum dot technology should grow from an estimated .6 million in 2008 at a compound annual growth rate of 90.7% to reach 1.1 million in 2013. Our solution should help with this market expansion, and is currently being used in solar and …
