Gallium-doped ZnO （GZO） nanorods were synthesized by microemulsion method with different types of surfactants. The phase and morphology of the above nanorods were investigated by scanning electron microscopy （SEM）, X-ray diffraction （XRD）, high resolution transmission electron microscopy （HR-TEM） and X-ray photoelectron spectroscopy （XPS）. SEM observations show that the ZnO nanorods have diameters around 70-200 nm and lengths up to several micrometers. The room temperature photoluminescence （PL） spectrum of GZO nanorods exhibited a sharp and strong ultraviolet bandgap at 383 nm and a relatively weaker emission associated with the defect level. Resistivity of GZO nanorods synthesized with sodium lauryl sulfate （SLS） and sodium benzene sulfonate （SBS） surfactants showed 2.84 Ω m and 14.2 Ω m, respectively.
