Abstract :
Highly conducting and transparent tin-doped indium oxide (ITO) thin films were deposited on glass substrates by spray pyrolysis. The characterisation of ITO thin films prepared under different deposition parameters is investigated. The transmission, resistivity and luminescence of the films were found to be strongly dependent on these parameters. The films prepared at the optimum conditions exhibit low resistivity and optical transmission larger than 90% in the visible region. ITO cathodoluminescence films prepared at 450degC and 500degC has been studied. These samples exhibit a strong luminescence peaks in visible region at 460 nm and 650 nm.
