Figure 1. Overview images showing varying PbS growth mechanisms by changing effective dilution.

Figure 1

Bright Field and Dark Field Scanning TEM overviews of the parent PbS solution diluted 1,000x (a & d), 2,500x (b & e) and 5,000x (c & f) centered on an area previously scanned at higher magnification. All panels depict evidence of ion diffusion causing nucleation and growth of nanoparticles in a region surrounding the square of initial electron irradiation. Scale bars represent 500 nm (d & e) and 250 nm (f).
