A low-cost and complexity-free demonstration of two relatively fast ultraviolet (UV) detectors based on ZnO nanosheets are reported in this letter for the first time. Highly crystalline ZnO nanosheets have been synthesized by a sonochemical method. The proposed UV detectors were fabricated through coating the synthesized materials on Cu electrodes. Experimentally obtained responsivity, detectivity, absorption, and I-V characteristics along with the quantum efficiency are reported. Comparison of the conventional ZnO photo-sensors with nanoparticle-based ones reveals that the proposed nanosheets photosensors have faster response time in the UV region, which might be attributed to low density of defect states (created during synthesis process) on nanosheets surfaces.
