采用化学气相沉积和超声处理的方法制备了氧化锌/还原氧化石墨烯复合材料。采用扫描电镜和X射线衍射对样品的形貌和结构进行了表征。在黑暗和紫外光照射下测量了探测器的电流-电压曲线。基于ZnO与RGO片结合的纳米复合材料的探测器显示出增强的光响应性能。此外，基于ZnO/RGO复合材料的器件的响应时间比基于ZnO纳米线的器件的响应时间快。基于ZnO/RGO复合材料的光电导紫外探测器有望在紫外探测领域得到广泛应用。
Zinc oxide (ZnO)/reduced graphene oxide (RGO) composite were prepared by chemical vapor deposition and subsequent ultrasonic treatment in this work. The morphology and structure of the samples were characterized by scanning electron microscopy and X-ray diffraction. The current–voltage curves of detectors were measured in darkness and under UV illumination. The detector based on the nanocomposite by combining ZnO with RGO sheets shows enhanced photoresponse performances. Moreover, the response time of device based on ZnO/RGO composite is faster than that based on ZnO nanowires. The photoconductive UV detectors based on ZnO/RGO composite may have a great application of ZnO in UV detection.
