摘要

In this study, co-doped ZnO rod arrays with wurtzite crystal structure were successfully prepared on zinc substrate by the co-precipitation method. The results of crystal analysis indicated that the dopant Co~(2+) was incorporated into ZnO crystal. Photolumi-nescence (PL) spectra and magnetization curves proved that their PL intensity and ferromagnetism were increased with the increase of Co~(2+) concentrations in a ZnO host. Current-voltage characteristic curves of Co-doped ZnO rod arrays indicated that as-prepared samples were n-type semiconductors. Co-doped ZnO rod arrays could be envisioned to detect diseases and bacteria based on these properties.
