| 摘 要： | 利用水热法合成花状的ZnO纳米棒,并对其进行X射线衍射(X-ray diffraction,xRD)与扣描电子显微镜(scanning electron microscope,SEM)表征.以该ZnO为敏感材料制成了旁热式结构气体传感器,测试了样品在不同温度下对丙酮气体的灵敏度.结果表明样品在290℃下对于丙酮气体具有高的灵敏度、快的响应恢复速度等特点.测试了传感器对于常见干扰气体的灵敏度,表明器件具有良好的选择性. |

| Abstract: | Flower-like ZnO nanorods were prepared with the hydrothermal method and characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The acetone sensing properties of the devices using ZnO films are investigated at different operating temperatures and acetone concentrations.The sensitivity to acetone is the maximum at the operating temperature of 290℃,and the sensor exhibits high sensitivity,rapid response and recovery,excellent stability and reversibility,and prominent selection to common interference gases. |
| Keywords: | ZnO acetone gas sensor nanostructures |
