The surface morphologies of nanostructure ZnO at different precursor concentrations were studied using scanning electron microscopy. Raman spectroscopy suggested that nanorods started to grow along with nanoflakes at a precursor concentration of 50mM and the density of the nanorods significantly increases when the concentration was raised to 75mM. Raman spectra were intensified and red shifted with the increment of precursor concentration. Optical properties of refractive index and optical dielectric constant are investigated. The structural defects at lower level of precursor were probably due to the hypoxic environment, whereas the red shift of Raman spectra was due to the structural change of ZnO nanocrystals 2013-01-10T06:12:54Z 2013-01-10T06:12:54Z 2012-02 Article Micro and Nano Letters, vol.7 (2), 2012, pages 163-167 1750-0443 http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=6156044 http://hdl.handle.net/123456789/22918 en Institution of Engineering and Technology (IET) |
