ABSTRACT
Nano-/micro-reactors have emerged as a powerful platform for chemical synthesis. Here, we develop fiber-spinning chemistry (FSC) based on a microfluidic blow spinning (MBS) technique, allowing the availability of nanoreactors for chemical synthesis with scale-up capacities. Proof-of-concept experiments focus on the utilization of MBS-derived fibrous nanoreactors for large-scale production of ligand-free perovskite quantum dots (PQDs) in one step. Typically, methylammonium lead halide (MAPbX3 , X=Cl, Br, and I) PQDs in situ synthesized at large scale inside polyacrylonitrile (PAN) nanofiber films (size 120â
cm ×30â
cm per hour), exhibit high photoluminescence (PL) quantum yield (QY) of 71 %, tunable emissive peaks (448-600â
nm), and superb PL stability. The PQDs/polymer nanofiber films are potentially useful for CO2 conversion, wide-color-gamut displays and light-emitting diode (LED) devices. These findings may guide the development of nano-/micro-reactor technology for scale-up production of nanomaterials with various potential applications.
