Abstract
A method for synthesizing nanostructures includes introducing a solution of seed crystals into an initial growth solution to form a nanostructure synthesis mixture. The initial growth solution includes a precursor material and a reducing agent in a surfactant solution. Growth of nanostructures in the nanostructure synthesis mixture is monitored during a period of anisotropic growth of the nanostructures to determine a shift from stage II growth of the nanostructures to stage III growth of the nanostructures. The shift from stage II growth to stage III growth is identified, and after identifying the shift, a second growth solution is added to the nanostructure synthesis mixture coincident in time with the shift. The second growth solution includes the precursor material and the reducing agent in the surfactant solution.
