(a) Scanning probe microscopy image ( scale is 10 nm and field of view is ) of silver nanoparticle growth on the domain of . (b) Localized nanowire formation due to subsurface defects ( scale is 5 nm and field of view is 300 nm).
Surface of showing evidence of production of silver nanoparticles. The inset shows the results of irradiation with a filter allowing irradiation of only 4.1 eV or below to pass where no silver deposition can be seen. The scale for both images is 10 nm and field of view is .
Proposed schematic for photoreduction of silver cations over domain where electrons are promoted into the and reduced silver cations and photoelectric reduction in silver cations over domain, where electrons are ejected from the surface of and reduced silver cations are bound to the surface in the stern layer. Here we have used as 3.9 eV and as 1.5 eV. NHE represents the reduction potential of the NHE in the system.
