    The laser sintering employing a CW DPSS laser was applied to the fabrication of transparent conductive films using silver and indium tin oxide (ITO) nanoparticle inks. The laser sintering of an Ag nanoparticle thin film gave a transparent conductive film with a thickness of ca. 10 nm, whereas such a thin film fabricated by conventional heat treatment using an electronic furnace was insulator because of the formation of isolated silver grains during the slow heating process The influences of the laser sintering conditions such as laser scan speed on the conductivity and the transparency were studied. The laser sintering using ITO nanoparticle ink gave a high transparent conductive film by one step scanning of laser beam in air.
