nanocrystals are continuously synthesized via a microreactorsystem consisting of poly(tetrafluoroethylene) (PTFE) capillaries. The synthesized nanocrystals possess excellent optical properties, including a full width at half maximum of 19–35 nm, high fluorescence quantum yield of 47.8–90.55%, and
quantum dots synthesized with a Br/I ratio of 1:3, a slight blue shift was observed for reaction temperatures greater than 100 °C. This PTFE-based microreactorsystem provides the unique capability of continuously synthesizing high-quality perovskite nanocrystals that emit over the full visible spectrum
with applications ranging from displays and optoelectronic devices.
