About the Journal :
Experimental and Theoretical NANOTECHNOLOGY (ETN) is a multidisciplinary peer-reviewed international journal published four issues a year. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of NANOTECHNOLOGY; with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics and materials science.
ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
Using zinc foils as the only starting material, we synthesized one-dimensional ZnO nanostructures (nanorods, nanoneedles and nanowires) in air by zinc vapor condensation method at 500oC.The morphology, structure and photoluminescence of the synthesized one-dimensional ZnO nanostructures were investigated with scanning electron microscopy, X-ray diffractometry, transmission electron microscopy and spectrophotoscopy. It is found that the size, shape and photo luminescent properties of the one-dimensional ZnO nanostructures depend on the growth time of ZnO in the furnace. Mechanisms on the growth of the nanostructures were discussed, and controllable morphology and photoluminescence of the ZnO nanostructures were achieved by varying the growth time of ZnO in the furnace. It provides a simple, energy-saving and environment benign route to synthesize one dimensional ZnO nanostructures with controllable morphology and emission properties.
