摘要: Abstract Nanostructured ZnO and Mg doped (Mg:ZnO) thin films were prepared on c -cut sapphire substrate at 700 °C by rf sputtering. The influence of doping the structural, luminescence, optical morphological properties investigated systematically. XRD pattern both show highly -axis oriented wurtzite hexagonal structure. A slight shift in (0 0 2) peak position establish effective into lattice. blue PL emission for Mg:ZnO film indicates modulation band gap caused addition, which is also confirmed increase energy value from 3.34 3.45 eV. significant change surface morphology nanowires nanoring, formed a novel self assembly process, highlights importance (20 at.%) ZnO.
