Growth and optical properties for non-catalytically grown ZnO micro-tubules by simple thermal evaporation
چکیده انگلیسی
A simple synthesis technique to grow ZnO micro-tubules in large quantities from ZnO powders in one step at ~ 1000 °C ± 50 °C is discussed. The micro-tubules were formed in the form of small chunks or ingots as well as sticking to the walls of the crucible. Most of those micro-tubules are formed radially outwards of the ingots and that self-alignment may be attributed to the local balance of vapors as well as the steady state of vapor flow. The morphology, structure and optical properties of ZnO microtubes were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy and Photoluminescence (PL) respectively. The growth of ZnO micro-tubules would be of interest in the future for the technological revolution of useful application such as in catalytic and optoelectronics.
