Synthesis And Characteristics Of Nano ZnO Without Catalyst

Nowadays nano-science and technology is one of the intensive science researches. Synthesis and Characterization of nano-materials is one of the vital fields of. nano-technology research. Quasi-one dimensional nanostructures, such as nanotubes and nano wires has the benefit for the study of electronic transmission, optical and the mechanical properties, such as the effects of their size and nature on the ideal system. The quasi-one dimensional nanostructures has been paid so much attention partly because of its special nature and structural performance out of the singular nature of mesoscopic physics; the feasibility between materials and microelectronics device design, processing technology, and nano-device manufacturing. The progress of nano-science and technology presents the prospect of manufacturing and integrating nano-photonics device.The progress of nano-science and technology can enhance the development of the device, whereas, the device manufactory development will also put forward higher requirements. ZnO is a wide-band direct bandgap semiconductor compounds with high exciton binding energy. T-ZnO with a three-dimensional spatial structure is considered to be filled with reinforced composite materials and organic materials as UV luminescence and photoelectric filling material with broad application prospects. Taking into account the T-ZnO nano-electronics, and other aspects of large-scale applications, the shape and size of T-ZnO free from defects must be controlled under proper growth condition. But in T-ZnO research, there are two main topics: Firstly, T-ZnO growth mechanism is not yet clear. Though several models dealing with their growth have been proposed, no clear evidence supports any model. Secondly, the growth condition of T-ZnO is not compatible with that of silicon IC technology. Therefore, the T-ZnO growth conditions have yet to be in-depth studyThe effect of temperature and growth duration on the growth of T-ZnO has been investigated in the present study. We further verify and discuss the T-ZnO nuclear growth physics to explore better growth conditions in order to control the growth of T-ZnO, and then discuss the influence of growth conditions on morphology and fluorescence properties. It is proposed that the growth mechanism of T-ZnO is similar to those of the two mechanisms of carbon nano-tubes.
