Abstract

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. (AU)
