Low Temperature Synthesis and Characterization of Zinc Oxide Nanorods by Simple Solution Process |
| 초록 |
Zinc oxide (ZnO) as an n-type semiconductor with direct wide band gap energy of 3.37 eV demonstrates great potentials for use in blue-ultraviolet (UV) semiconductor lasers, light emitting diodes, and other optoelectronic devices.Due to its wide application, we report synthesis of uniform zinc oxide nanorods by a simple solution method using zinc chloride as a precursor material, and ammonium hydroxide (NH4OH) as a hydroxyl ion (OH-) source without using any additive molecules at 60 0C reaction temperature via refluxing. The generation of as synthesized zinc oxide nanorods from wulfingite zinc hydroxide microcrystal have also been discussed via time-dependent reaction process.The crystallinity and structural properties of as synthesized zinc oxide nanorods were further characterized by X-ray powder diffraction (XRD), transmission electron microscope (TEM), high-resolution TEM (HR-TEM), field emission scanning electron microscope (FESEM),Fourier transform infrared spectroscopy (FT-IR). Optical activity of as synthesized products was characterized by UV-Vis spectrophotometer. |
