ITO Obtained by Spray Pyrolysis and Coating on Glass Substrate

Conductive thin films have various applications in different technological fields.Indium tin oxide (ITO) is a mixed oxide.In the film form, ITO has been widely employed as electrode in many optoelectronic devices.Methods like thermal evaporation, sputtering, chemical vapor deposition (CVD), electron beam, spray coating, and sol-gel synthesis give ITO thin films.In this work, we prepared ITO thin films by dip coating of a glass substrate into ITO obtained by spray pyrolysis.ITO consisted of spherical particles with different diameters.The ITO thin films were treated with laser.X-ray diffraction (XRD) analysis confirmed that spray pyrolysis produced spherical ITO particles.Transmittance analyses revealed the production of transparent films with thickness ranging from 0.800 to 1.200 μm.The four-wire test showed that the porosity of the films led to low conductivity.Film resistance was a function of the number of layers of ITO thin film.
