Abstract :
Absorption spectra and surface topography of optically modified silver nanoparticles grown on ITO thin layers are here investigated. The study is carried out with two ITO layers respectively having 50 Omega/square and 4 Omega/square sheet resistivity. The surface of the Ni samples are treated by one, three and five single pulses of 20 ns Nd:YAG laser. After the irradiation processes, the grating-like structures of various periods are observed. The result obtained is mainly assigned to the concentration of free electrons that is responsible for the surface plasmon resonance and the heat transfer phenomenon.
