摘要：
We found that UV laser irradiation on a ZnO seed layer induced the crystal orientation at the surface, consequently leading to the growth of densely aligned ZnO nanorods on such a laser-irradiated layer. A single nanosecond pulse with a wavelength of 266 nm was irradiated to a ZnO seed layer on a glass substrate, and then, ZnO nanorods were synthesized on a laser-treated layer by a hydrothermal method. Electron microscopic observations revealed the growth of highly oriented ZnO nanorods on a laser-irradiated seed layer as well as the orientation of seed layer crystals to [0001].
