Low-Temperature Rapid Fabrication of ZnO Nanowire UV Sensor Array by Laser-Induced Local Hydrothermal Growth

Figure 1

Schematic illustration of laser-induced hydrothermal growth process. The target substrate is seeded with ZnO NP, and immersed in the precursor solution. The laser is then focused on the sample surface to generate a confined temperature field to induce localized synthesis of ZnO NW.
