Transparent conducting ZnO:Ti films with high transparency and relatively low resistivity were successfully prepared by DC frequency magnetron sputtering at room temperature. The effects of the distance between target and substrate on the structures, morphologies and optic-electronic properties of ZnO:Ti films were investigated. The experimental results show that the distance between target and substrate is an important factor to the crystal structure and optic-electronic properties of ZnO:Ti films. XRD studies reveal that all the films are polyerystalline with a hexagonal structure and a preferred orientation along the e-axis. The lowest resistivity achieved is 4.18 × 10~(-4)Ω·cm at 4.6 cm distance between target and substrate.All the films present a high transmittance of above 92％ in the visible range. ZnO: Ti films with high transparency and relatively low resistivity deposited at room temperature will be used as transparent electrode in thin film solar cells and liquid crystal display.
