Abstract
An apparatus for accelerated multi-stage synthesis of quantum dots (QDs) includes an injector which injects a material for producing QDs, a first reactor connected to the injector and including at least one selected from a coil reactor and a plate reactor, a second reactor connected to the first reactor and including at least one selected from the coil reactor and the plate reactor, and a first junction connected between the first reactor and the second reactor and provided with an inlet for injecting the material for producing the QDs.
