Hydrothermal synthesis, structural and optical investigations of undoped and Mg doped ZnO nanorods

Undoped and Mg doped ZnO nanorods were synthesized by sol gel and hydrothermal method. Vertically aligned ZnO nanorods were sequentially characterized for structure(XRD), morphology(FESEM), Optical properties(UV-Vis) and electrical properties (I-V).XRD studies indicates a significant c-axis compression and reduced crystallite size for the Mg doped sample as compared to undoped ZnO nanorods, which was further confirmed by FESEM images. Decrease in optical band gap (3.14 eV) and enhancement in photocurrent density (6.67 mA/cm2)was observed incase of the doped sample. All these results indicates that 5 % Mg doped ZnO can be suitably used for applications in optoelectronic devices.
