Contral Growth And Uv Detect Properties Of Mg-Doped Zno Nanostrctures

ZnO is wide band gap semiconductor material, which has a big potential in photoelectric functional areas. ZnO-based one-dimensional nanostructure materials offer better optical properties and crystal qualities compare with body materials or two-dimensional film structures, which become a hot spot in materials research field recently. Acquire a kind of band gap adjustable ZnO nanostructure materials through doping Mg element into ZnO crystal lattice, future, the preparation of response wavelength tunable ultraviolet photoelectric device or applied in a more wider range field.In this article, we used chemical vapor deposition (CVD) method to synthesize pure vertical ZnO nanowires, Through the characterization of samples, we comprehensive analysed kinetics of ZnO nanowires crystal growth process by vapor-solid (V-S) mechanism under CVD method. We used the same CVD method to synthesize Mg-doped ZnO nanowires. A kind of ZnO/ZnMgO core-shell structure nanowires were fabricated by hydrothermal and atomic layer deposition (ALD) method. Make use of ZnO/ZnMgO core-shell structure nanowires, we obtained a kind of photoconductive UV detector that narrow band response at364nm to378nm. Finally, we obtain a large areas self-supporting Ag-doped ZnO nanoarray with transport freely and research its optical properties.
