Single-particle spectroscopy of CsPbBr3 perovskite reveals the origin low electrolumine

[ad_1]

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,…
