2018 – 2019
The effect of terbium doping on the optical, electrical and light emission properties of sputtered indium tin oxide and aluminum doped zinc oxide thin films will be investigated for different annealing conditions and dopant concentrations. The films will be prepared by RF magnetron sputtering maintaining a high transmittance in the ultraviolet, visible and near infrared spectral regions and a fairly low sheet resistance. In order to induce the activation of terbium luminescent centers, the films will be annealed up to 700°C under distinct atmospheres, high vaccum, air and oxygen. The variation of the terbium related integrated light emission intensity versus de annealing temperature and the impact on the optical and electrical properties are of main interest in this project. Optical transmittance, electrical resistivity and X-ray diffractometry will be registered after each annealing process to assess the compromise between the achieved light emission intensity and optical and electrical properties.
