In recent years, ZnO nano-structured materials in the preparation of nano-electronic components played a huge potential, and gradually people's attention. At present, the ZnO-nanostructures materials have been used in the field of manufacture of the field effect transistors, single electron transistors, photodiodes, nanosensors, nanodevices. Novel ZnO nanostructures has gradually come out, such as nanowires, nanorods, nanotubes, nano-nails, nano spiral, hollow spheres and dandelion structure. In all the material for the preparation of one-dimensional nanomaterials, ZnO is the most widely used wide band gap semiconductor material. ZnO nano-structured materials with a wide band gap (3.37eV), the exciton binding energy (60 meV), good chemical and thermal stability, high transmittance, good biological compatibility, and a large range of conductive significant advantage, has been used in the emerging field of nanotechnology. ZnO nanostructures can be formed living in the first of all substances, known as all substances in most nanostructures of a substance. Currently, there have been many reported using different methods of preparing ZnO nanostructured materials, such as molecular beam epitaxy (MBE), pulsed laser deposition (PLD), sputtering, electrochemical deposition, vapor phase transfer method (VPT), ??chemical vapor deposition (CVD), thermal evaporation. An efficient way as the growth of ZnO nanorods / nanowires, aqueous solution method due to its low cost, low temperature operation and environmental coordination and other significant advantages gradually been widespread concern. The thesis is divided into two parts: First, the use of aqueous solution at 95 ° C lower temperature of ZnO nanorod arrays on different substrates (quartz glass, silicon, and ITO glass) and on the substrate of ZnO nanorods array structure, morphology and optical properties were analyzed. X-ray diffraction (XRD) and scanning electron microscopy (SEM) results showed that, in three substrate can be grown ZnO nanorod arrays of hexagonal cylindrical morphology are more compact and neat. The ZnO nanorods average diameter and length and the nature of the substrate are closely related. By room-temperature photoluminescence (PL) spectrum test shows that the use of aqueous solution of ZnO nanorod arrays on different substrates have good optical properties. And Raman spectra of the conclusions were further proof. Second, the use of an aqueous solution of ZnO nanorod arrays grown on the silicon substrate. Obtained ZnO nanorod arrays were characterized by XRD and SEM. The results showed that the the hexagonal cylindrical ZnO nanorods along the c-axis direction is uniform and dense growth on a silicon substrate. The room temperature PL spectra show that the application of an aqueous solution method can be grown with good optical properties of ZnO nanorod arrays. Using synchrotron radiation X-ray absorption near edge structure (XANES) spectroscopy testing, analysis radius of the local electronic structure of ZnO nanorods on the oxygen K band edge of the ZnO nanorod array. A comparative study of the local electronic structure of ZnO nanorods and ZnO thin films.
