AbstractColloidal quantum dots are materials of interest in infrared detection - a consequence of their near-infrared light harvesting capability, tunable bandgap, and solution-processing. Herein we develop a quantum-dotin-perovskite-nanowire consisting of PbS quantum dots embedded inside MAPbI(3) nanowires. The kinetics of perovskite nanowire growth were tracked. We found that N,N-dimethylformamide induced the formation of perovskite nanowires, and that their growth was accelerated upon PbS quantum dot inclusion. We then used this nanocomposite to fabricate photodetectors that showed a light response from the visible to near infrared region up to 940 nm. Finally, a flexible photodetector was fabricated on a polyethylene terephthalate substrate.
