Abstract
In this study, the effect of doping concentration on the morphological, structural and optical properties of Zn1−xMnxO 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 381nm and a strong emission around 552nm 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.
