N2 - Transparent conducting ZnO and Zn0.97Nd0.03O films were deposited on chemically cleaned glass substrates at 723 K through the spray pyrolysis method. All deposits were shown hexagonal wurtzite structure with polycrystalline nature having prominent (1 0 1) plane. The films exhibited fibrous surface morphology. Above 80 % transparency in the visible region and bandgap of 3.25 eV was noticed. The extinction coefficient of the deposits is estimated for different wavelengths. The presence of zinc and oxygen-related defects were noticed in the deposits through photoluminescence spectrum analysis. Silver showed good ohmic contact material for all the deposits. All deposits showed n-type conductivity. Zn0.97Nd0.03O showed lesser resistivity and higher carrier concentration. Hence, Zn0.97Nd0.03O films can be used as a good transparent oxide material for opto-electronic applications.
