Sumario:[Image: see text] The production of nanoparticles on an industrial scale requires an approach other than the widely used hot-injection method. In this work, two heat-up methods are applied to nanoparticle synthesis. The induction heating method produces CdSe quantum dots with ultrasmall properties in seconds. Initial flow-through experiments demonstrate that induction heating continuously produces quantum dots. These results are compared with those from microwave synthesis, which produces quantum dots on a longer timescale but provides fast, continuous heating. Both methods can produce quantum dots within seconds because of rapid heating. In addition, different precursors, single source and separate source, give different results, ultimately providing a handle to control quantum dot properties.
