摘要：
Two-dimensionally Ordered macroporous films have attracted attention for their potential application such as sensors and optoelectronic devices. Here, highly ordered ZnO nanonets film were successfully prepared by a facile method, which uses monolayer colloidal crystal template composed of polystyrene spheres and sol-gel spin-coating method. Furthermore, ZnO nanonets-based ultraviolet photodetector are constructed, which showed high on/off current ratio of 2.7 x 10(5) under 370 nm UV light illumination with an intensity of 0.85 mW/ cm(2).
