ZnO纳米棒的制备及紫外探测性能

摘要

ZnO nanorods (NRs) were successfully fabricated on ITO substrates by hydrothermal method,and UV detector of ZnO NRs was prepared with ITO as electrode. The UV properties of the devices were tested at room temperature. The results confirm that the ZnO NRs have an excellent re-sponse to UV light and the sensitivity of ZnO NRs UV detectors can reach 1 500 closing to 0 V. In addition,it can be seen that the ZnO NRs UV detector has good repeatability and stability in the cy-cle test.%通过水热法在ITO衬底上成功合成了ZnO纳米棒,并以ITO为电极制备了ZnO纳米棒紫外探测器件.在室温下测试了所制备器件对紫外光的响应性能.测试结果表明,ZnO纳米棒对紫外光有很好的光响应,在0 V附近,ZnO纳米棒紫外探测器的灵敏度能达到1500.此外,通过循环测试可以观测到ZnO纳米棒紫外探测器具有良好的重复性和稳定性.
