Caption

Top: Single-particle photoluminescence imaging of the halide exchange reaction using the flow reactor. The light emitted changed from red to green while the crystals maintained their morphology and light-emitting efficiencies. Below: Illustration of structural changes to the perovskite nanocrystal caused by the halide exchange reaction. The dark state is caused by insufficient electric charge for light generation, which resulted from the disruption of the crystal's inner structure (defects).
