Quantum Dots (QDs) are semiconductor nanocrystals; whose size, shape, chemical composition, and inter-particle connection play key roles in determining their physical and chemical properties. Monodispersed QDs with narrow size distribution are crucial
for various QD-based applications, including bio-imaging, photo-catalysis, and optoelectronics. Nevertheless, scaling up the material synthesis via the traditional batch method lessens crystal quality and monodispersity, due to reduced control of
the reaction conditions; and thus the nucleation and growth processes. In our lab, we adopt the continuous-flow reactor synthesis approach to synthesize a wide range of nanocrystallites and QDs, in large-scale, while maintaining precise control of
the reaction conditions (temperature, reactions time, etc..). Our aim is to develop automated synthesis procedures of high-quality materials in order to support QDs in fulfilling their tremendous industrial promise in various applications.
