Research Abstract |
The fabrication method of the ZnO nanosheets has been established, where the ZnO nanowalls are synthesized by nanoparticles-assisted pulsed laser deposition and then the nanowalls are lifted off by laser irradiation form a substrate. Nano-structuring of on the nanosheets has been achieved by Ga ion beam and laser processing using silica micro lens. It is also proposed that an irregular-shaped ZnO nanosheet acts as a random laser chip. Based on this idea, the random lasing in a single irregular-shaped ZnO nanosheet with a low threshold power of 150 kW/cm2 is successfully demonstrated.
