| Sumario: | There currently exists some debate as to exact mechanism of cation exchange in semiconductor nanocrystals, a crucial question regarding the fundamental materials chemistry of these systems. Here, the authors report a detailed investigation of the mechanism of cation exchange in nanocrystals, which unambiguously shows evidence of interstitial intermediates during the exchange process. |
