Conductive glass coating: Effect of atmospheric plasma treatment

The application of conductive glass coating in recent years plays a significant role in research and commercial laboratories. We report the change in conducting property of Cu-Ti-Cl thin film coating onto glass substrate as a function of atmospheric pressure plasma (Ar+) treatment (upto 15 minutes). This metal-transition metal chloride coating is prepared by chemical solution process where polyvinyl alcohol (PVA) is used as a chelating agent. The UV-Vis absorption spectra reveal that the optical band gap of the thin film varies from 1.71eV to 2.51eV. A reduction in dc static resistance (2.1MΩ to 0.5MΩ) of the film is obtained from the voltage-current characteristics. The X-ray diffraction peak intensity also reduces with treatment time.The application of conductive glass coating in recent years plays a significant role in research and commercial laboratories.
