Self-Assembly Of Quantum Structure Of Amorphous ZnO, Nanocrystalline ZnO & Study Of Optical Properties

The self-assembly of quantum structure is a new science concept, which unifies the chemistry and physics, organic and inorganic, and so on. The process using self-assembly to construct quantum structure in mesoscope will greatly promote the development of integrated circuits, microelectronics, nanoelectronics and further, to molecular electronics. The self-assembly of quantum structure is being one of the hottest fields in solid physics, material chemistry, and nanoscience.The treatise starts from self-assembly of quantum structure, providing several methods to construct nanomaterials: 1. This part emphasizes the synthesis of nanoarrays, aiming at controlling the size and distance of nanocrystallites using calixarene derivatives by altering the size, length and chemical structure of the organic molecules; 2. This part emphasizes in situ synthesis strategy for fabrication of polymer network of ZnS based nanopowder, aiming at size controls, coating and preventing agglomeration following 'one-pot' synthesis; this method fits to low cost, large scale production; 3. According to development in ZnO nanomaterials, we first report on the synthesis, characterization of amorphous ZnO, aiming at describing the principles and approaches of synthesis techniques, optical properties, spatial structure and doped effect; the amorphous ZnO displays cage-like structure, showing a strong ultraviolet emission while the visible emission is nearly fully quenched, a potential UV- emission material; 4. This part focuses on the system of amorphous ZnO/nanocrystalline ZnO, aiming at describing 3D confined quantum structure,interface properties associated visible emission using optical detecting; 5. This part emphasizes the synthesis techniques, aiming at processing size controls and high quality of the ZnO nanomaterial using solid-state pyrolytic reaction; 6. The final part focuses on growth of high orientation ZnO thin films, aiming at describing the physical mechanism, synthetic techniques for understanding the morphology, surface and microstructure and outcoming strong UV- emission. We believe the presented approach will be useful in semiconductor theory, promoting the development of integrated optoelectronics, and practical application to optoelectronic devices.
