| Description |
The low temperature mineralization of zinc oxide nanorod
bunches from zinc precursor solution mixed with the cationic
surfactant Cetyl Trimethyl Ammonium Bromide is reported. Five different combinations of zinc precursor and surfactant ratios are chosen and their properties are compared using the average particle size, lattice parameter ratio (c=a) of hexagonal ZnO from X-ray diffraction, the morphologies from SEM, TEM and their optical characteristics by using optical absorption spectroscopy spectrometry. A surfactant lowers the surface tension of the
solution, and forms a thermodynamically ordered and a disordered
phase wherein, ordered phase seeds the growth of the ZnO
nanostructures. A peculiar circular structure called `micelle' is
formed by the surfactant. The heads, located on the peripheries
of the micelle, are the ordered phase in the solution, and are the
original nucleation sites of the Zinc Oxide nanostructures. This fashion of nucleation is the reason for the `arms of the wheel like morphology consisting of nanorod bunches. Out of the five
combinations experimented, the 3:1, 3:2, 1:1 ratios show nearness in the standard c=a value. The photoluminescence spectrum shows UV emission in the region of 380 nm and weak blue emission.
The UV-VIS-NIR spectrum has exhibited a characteristic UVabsorption.
