Microscopic Emission Image of Aggregates Formed by Nanocrystals of the Perovskite CsPbBr3

Caption

Intensity time trace of photoluminescence of one aggregate (middle, top) shows no fluctuations because all nanocrystals within the aggregate emit simulatenously (middle, bottom scheme); Intensity time trace of electroluminescence of one aggregate (right, top) shows strong fluctuations (blinking) because all charges are funneled to one nanocrystal which is emitting (right, bottom scheme).
