Fabrication and Characterization of Direct-Patternable ZnO Films Containing Pt Nanoparticles

Abstract

The optical and electrical properties of ZnO films incorporating 0.25 at. % Pt nanoparticles were studied. Pt nanoparticles were synthesized by a methanol reduction method and their size was controlled to 3 nm on average using poly(N-vinyl-2-pyrrolidon) as a protecting agent. The electrical conduction of the ZnO films was enhanced by the introduction of Pt nanoparticles without degradation of the optical transmittance. Well-defined 60-mu m-wide direct-patterned ZnO films containing Pt nanoparticles were formed by using photosensitive ortho-nitrobenzaldehyde as a stabilizer to contribute the formation of a crosslinked network structure during a photochemical reaction.
