Abstract

Ag nanoparticles with a narrow size distribution were prepared by spontaneous reduction of Ag 2-ethylhexanoate in dimethyl sulfoxide. According to the incorporation content, SnO₂ film transmittance was slightly reduced by light absorption of incorporated Ag nanoparticles. With incorporation of Ag nanoparticles, the crystallinity of the SnO₂ films slightly decreased and the film sheet resistance improved. The valence band maximum of SnO₂ films containing Ag nanoparticles indicated a shift towards the Fermi energy level, corresponding to an increase of electrons in the valence band from electron transfer from the Ag nanoparticles to the film. Direct-patterning of SnO₂ films with Ag nanoparticles was produced without photoresist or dry etching. These results suggest a micro-patterned system can be simply fabricated with low cost and the electrical properties of the SnO₂ films can be improved by incorporating Ag nanoparticles.
