ZnO and Ag-doped ZnO nanorods are fabricated by hydrothermal method. Effects of Ag doping on the ZnO nanorods have been investigated by various measurements. Introduction of Ag in ZnO nanorods has no effects on the surface morphology and growth habits of ZnO. Compared to ZnO nanorods, absorption wavelength shifts red after Ag doping, corresponding to decrease of optical band gap. It is suggested that defects band is introduced into Ag-doped ZnO. Luminescence of Ag-doped ZnO nanorods have been found to have two emission peaks centering at around 520 nm and 680 nm, which can be explained by oxygen vacancy and introduced defects, respectively. ZnO and Ag-doped ZnO nanorods inorganic/organic heterostructure LEDs are reported. The junction consists of nanorods and polymer, which is evaporated or spin-coated on the samples. Ag doping ZnO nanorods inorganic/organic heterostructure LED shows smaller leakage current and better rectification characteristic than pure ZnO nanorods LED device.
