| Abstract: | We report on structural and optical changes induced by impurity incorporation in ZnO nanorods grown via electrodeposition. We find the lattice parameters of the hexagonal ZnO rods to be larger than in defect-free single-crystalline ZnO. SIMS measurements indicate impurity incorporation and doping in the bulk of the nanorods. The impurity content correlates with changes in the electroluminescence spectra. The maximum of the defect luminescence band around 600 nm shifts towards longer wavelengths with metal incorporation. Aluminum incorporation leads to a narrow luminescence band close by the bandgap of ZnO around 390 nm. |
