Study on the structural and optical properties of Ga-doped ZnO nanorod arrays |
| 초록 |
Highly oriented Ga-doped Zinc Oxide (ZnO) nanorod arrays have been prepared on a ZnO-buffered silicon substrate in an aqueous solution which is a mixture of methenamine (C6H12N4), gallium nitrate hydrate (Ga(NO3)3.xH2O) and zinc nitrate hexahydrate (Zn(NO3)2.6H2O). The microstructures of nanorod arrays were analyzed through different characterization techniques including XRD, XPS and FESEM. The experimental results show that Ga-doping level plays a key role in the formation of ZnO nanorods, while the concentration ratio of zinc nitrate hexahydrate to methenamine also affects the morphology of nanorods. The effects of Ga-doping level on the optical properties of ZnO nanorod arrays were characterized using He-Cd laser as excitation source and discussed in detail later. These Ga-doped ZnO nanorod arrays may be used in electronic and optoelectronic applications. |
