Effect of growth time on the structure, Raman shift and photoluminescence of Al and Sb codoped ZnO nanorod ordered array thin films

► Al and Sb codoped ZnO nanorod ordered array thin films were synthesized using hydrothermal method. ► These films have great Raman shift of 15 cm−1 to lower wavenumber and have low asymmetrical factor Гa/Гb of 1.17. ► These films have more donor-related PL.
