Vertically aligned Fe-doped ZnO nanorod arrays (ZnO:Fe NRAs) with weak ferromagnetism at room temperature (RT) have been fabricated by in situ doping of Fe into ZnO nanorods (NRs) using a simple thermal chemical vapor deposition method. Structure analyses indicated that the NRs have a single-crystalline wurtzite structure without any detectable segregated cluster or impurity phase. Both photoluminescence and electroluminescence (EL) showed near-band-edge and broad defect-band emissions at RT. The EL from ZnO:Fe NRAs/p-Si light-emitting diodes red shifted with increasing current injections, which was ascribed to the doping effect of the Fe. [ABSTRACT FROM AUTHOR] |
