| 摘 要： | 研究了WO3掺杂的ZnO基气敏元件在紫外(UV)光激发下,对乙醇气体的室温气敏性能。结果表明:在UV光照射下,各元件在室温下对体积分数为100×10–6的乙醇气体显示了很好的光敏、气敏性能,响应、恢复时间均在8s以内,其中以掺杂X(WO3)为1%的元件W(1)为最佳,从而实现了室温下的气敏测试。

| Abstract: | UV light enhanced ethanol sensing properties of WO3-doped ZnO sensors at room temperature were investigated. The results show that all the sensors have excellent opto-and-gas sensitive property to 100×10–6 of ethanol vapor under the UV light activation simultaneously at room temperature. There are rapid response and recovery time within 8 s for all the sensors and the sensor W(1) with doping 1% WO3 (population fraction) show the best gas sensing property. Using this method, the gas sensing test at room temperature can be achieved. |
