Abstract

The effects of the incorporation of one-step synthesized Pt nanoparticles on the crystallinity as well as optical and electrical properties of direct-patternable SnO2 thin films using a photosensitive additive were investigated. As the heating time increased, the color of the one-step synthesis solution changed from transparent to black due to the formation of Pt nanoparticles. The optical transmittance of the films was not affected as the heating time was increased. However, the crystallinity of the films increased with increasing heating time. In addition, the resistivity decreased because Pt nanoparticles were synthesized during the long solution heating time and the reduction of SnO2 progressed. One-step synthesis of Pt nanoparticles enhanced the electrical properties of direct-patternable SnO2 thin films without significantly degrading their structural and optical properties. Direct-patterning of SnO2 thin films after spin coating was successfully performed with a line-width of 30μm.
