This technology is a continuous-flow injection reactor and a method for continuous material synthesis, including the continuous synthesis of nanoparticles. The reactor features a mixing zone unit and a removable residence time unit coupled to the mixing unit. The mixing unit includes a series of inlets for reactant solutions to combine and form nucleated nanoparticles which flow through the residence time unit consisting of a single conduit or multiple tubes. The mixing and nucleation takes place within a temperature controlled environment, and numerous semiconductor compositions can be synthesized with this process.

Background of Invention
Nanocrystalline semiconductors have attracted a considerable amount of attention due to their unique physiochemical properties. Recent advances in nanocrystals are having a dramatic impact on the development of next generation low-cost and/or high-efficiency solar cells. Conventionally, small-scale batch processes have been used to synthesize nanocrystals. However, agglomerated, amorphous nanoparticles are obtained and high –temperature annealing may be required to achieve a desired crystalline structure. Researchers at Oregon State University have discovered a new method and reactor for continuous production of materials such as nanoparticles.
This technology has been successfully tested in the lab and is seeking potential licensees. Issued US Patent No. 8,801,979
