Continuous Manufacturing of Lead-free Halide Perovskite Nanocrystals Using a Microreactor System

The objectives of this project are 1) to develop PTFE (polytetrafluoroethylene)-based microreaction systems with in-line monitoring for continuous synthesis of inorganic halide perovskite Pb-free nanocrystals (NCs), whose emission light covers the spectrum of UV-visible light, and 2) to investigate the fundamental mechanisms controlling the growth of inorganic halide perovskite Pb-free NCs in the microreaction systems. This project will integrate the information from materials processing, materials characterization, and numerical analysis to answer two basic questions: 1) What are the mechanisms controlling the growth of inorganic halide perovskite Pbfree NCs in the PTFE-based microreaction systems; 2) How does fluid flow influence the growth of inorganic halide perovskite Pb-free NCs? Results of this work will fundamentally transform the understanding of the growth of inorganic halide perovskite Pb-free NCs in the PTFE-based microreaction systems by uncovering the effects of fluid flow on the growth of NCs, and beneficially impact the scale-up production of NCs with the desired properties.
