摘要： 采用水热法在不加任何助剂的情况下制备了六方纤锌矿ZnO及掺杂钐的ZnO (ZnO:Sm)粉体材料. 气敏测试结果显示，ZnO:Sm材料对二甲胺具有较高的灵敏度，随着二甲胺浓度增加，灵敏度呈现线性增加，当二甲胺气体的浓度为1.00′10-4时该气体传感器的检测灵敏度可达到63.97. 在三甲胺气氛中，ZnO:Sm对二甲胺具有优异的选择性，对二甲胺的响应时间为6 s，恢复时间为19 s.

Abstract: The hexagonal wurtzite ZnO powder and samarium-doped ZnO powder (ZnO:Sm) were prepared by environment-friendly hydrothermal method without using any assisting agents. The gas sensing results show that the ZnO:Sm material exhibits better sensitivity towards dimethylamine. Its sensitivity increases with increasing of dimethylamine concentration. When the concentration of dimethylamine is 1.00′10-4, the sensitivity reaches 63.97. Moreover, in the atmosphere of trimethylamine, the sensitivity of ZnO:Sm towards dimethylamine exhibits excellent selectivity. The response time is about 6 s, and the recovery time about 19 s.
