Abstract: In this project, Zn1-xMnxO nanorods and thin films were fabricated by hydrothermal and rf magnetron sputtering methods respectively. The magnetic properties of Zn1-xMnxO derived from different routes have been studied and reported extensively. In this study, efforts were put into the fabrication of the Zn1-xMnxO nanorods and films and their optical properties. The growth conditions of both methods showed different effects on the morphologies of Zn1-xMnxO structures. The XRD spectra for Zn1-xMnxO nanorods and films showed peak shift, solidifying the fact that manganese was successfully doped into ZnO lattice. UV-Visible (UV-Vis) absorption and photoluminescence (PL) measurements were applied to study the optical properties of the nanorods and films. Low temperature PL was also used to further understand the detailed optical properties for hydrothermally grown nanorods. Some changes of the PL and UV-Vis absorption spectra were observed due to the introduction of Mn into ZnO, consistent with the structural characterization.
