Abstract
An efficient photoinduced method to operate by average sizes and heights of silver nanoparticles deposited on transparent and conductive substrates by seed-mediated growth method is proposed. The study is carried out with indium tin oxide (ITO) and fluorine doped tin oxide (FTO) substrates having 4 and 14 Ω/square sheet resistance, respectively. These two substrates determine different photoinduced aggregation of silver nanoparticles. The substrate resistance appears as the principal origin of the observed photoinduced aggregation features. The nanosecond kinetics of phototransparency engenders temporary oscillations in the range of nanosecond time. Several roles of the local overheating occurring through the electron-phonon interactions are evidenced.
