Transparent Conductive Films by Laser Sintering of Metal Nanoparticles

Abstract

The number of spin-coating times of ZnO nanoparticle layer on the transmission and conductivity of the Ag/ZnO dual layer film have been investigated, where the Ag film was prepared by laser sintering method following a spin-coating of Ag nanoparticle ink. The transmittance increased about 10% in the visible region and the peak transmittance shifted toward the longer wavelength with increasing in the thickness of ZnO layer. The ρs of the dual layer film kept as low as 2.7 Ω/sq with the number of spin-coating times less than 8, and then the ρs rose to 93.4 Ω/sq with increasing in the spin-coating times.
