One dimensional ZnO nanostructures have been extensively studied and applied in diverse fields, due to their wide bandgap semiconductor property, piezoelectricity, large exciton binding energy, anisotropism and low dimensional nanostructure characteristics. Many routes can be adopted to grow diverse morphological onedimensional ZnO nanostructures which have been used in different fields such as nanogenerators, solar cells, photoelectrochemical water splitting, light emitting diodes, lasers, gas sensitive devices, spin electronics, etc. However, there are many shortcomings in onedimensional intrinsic ZnO nanostructures, which limit their applications. In recent years, the onedimensional doped ZnO nanostructures have drawn great attention since doping can enhance or give them some novel and peculiar characteristics. This article gives a comprehensive overview of the progress of onedimensional doped ZnO nanostructures that has been made within the context of doping types, including ndoping, pdoping, diluted magnetic semiconductor doping, etc. Furthermore, the problems for the doping of onedimensional ZnO nanostructures have been discussed, and the prospect of further research and development have been proposed.
