Abstract

Cation doping is a practical way of engineering the optical properties of one-dimensional semiconductor nanomaterials, such as their band gap. We have grown zinc oxide (ZnO) nanorods doped with sodium cations (Na+) using a hydrothermal method at temperatures as low as 60 °C. We have investigated the effect of different concentrations of Na+ on structural and optical properties and morphology of the ZnO nanostructures. We have also simulated and discussed the chemical route of formation of doped and undoped ZnO nanorods. We found that, for low-temperature hydrothermal doping of ZnO nanorods with Na+, the optimum concentration ratio of zinc to sodium precursors is 1:10.
