(Left) In-line photoluminescence spectroscopy of the Cl (blue) and I (red) exchanged CsPbBr3 (green) nanocrystals, along with local and long-range G(r) (center and right, respectively). Local first nearest neighbor and full G(r) of CsPbX3 nanocrystals formed from halide exchange. The dotted lines show the shift in first-nearest-neighbor correlation in going from Cl exchanged nanocrystals (blue), parent Br (green) and finally I exchanged nanocrystals (red). |
