Figure 5.

Time-resolved normalized differential absorption intensity measurements of SnO2NWs excited with 4.0 eV and probe at 4.0 eV. The different curves correspond to different incident absorption fluence of the NWs. The inset shows the fits (solid lines) to the actual differential absorption data (points) using a simple model which includes multi-exponential decays and Auger recombination
