Abstract
In this study, the effect of doping concentration on the morphological, structural and optical properties of Zn1âxMnxO nanorods synthesized by solvothermal technique has been investigated. The morphological studies showed nanorod-like morphology and the preferential growth direction along the c-axis. The doping of Mn2+ ions has significant influence on the optical properties of ZnO nanorods. Room-temperature photoluminescence spectra of Mn-doped ZnO nanorods exhibit a weak emission at 381Â nm and a strong emission around 552Â nm and the spectra also indicate that the concentration of the defects increased by doping. The dynamic process of the UV absorption for Mn-doped ZnO nanorods was discussed in detail.
