Scanning electron microscopy images and size distribution histograms. Scanning electron microscopy images and size distribution histograms of immersion time and pulse length dependent size distribution of AgNPs. From (a-e) the pulse length τ = 0.5 s with different immersion times: (a) t = 10 s, (b) t = 20 s, (c) t = 30 s, (d) t = 40 s, and (e) t = 50 s. (f) Pulse length τ = 1 ms and t = 50 s. Insets are histograms of the particle diameter. The scale bars in all Figures are 200 nm.
