| 摘 要： | 把超声波和低温陈化技术运用到共沉淀法中,制备出了纳米ZnSnO3粉末.XRD和能谱分析表明为纯的ZnSnO3相.TEM分析表明粒度小于40nm.以ZnSnO3为基体的气敏元件对乙醇的灵敏度和选择性都很好,并且对汽油的抗干扰能力强.通过SEM对敏感层的分析解释了气敏特性的成因. |

| Abstract: | With the application of supersonic wave and hypothermia ageing technology to the coprecipitation method,pure nano-ZnSnO_3 powder was prepared.Energy spectrum,X-ray diffraction(XRD) and transmission electron microscope(TEM) analysis indicated that the final powders were ZnSnO_3 and the mean crystallite size of the powder was less than 40 nm.The sensor based on ZnSnO_3 showed a good sensitivity and selectivity to ethanol.And interference rejection to gasoline was excellent.The reason could be explained by sensitive layer analysis with scanning electron microscope(SEM). |
| Keywords: | nanometer preparation hypothermia ageing supersonic wave gas sensitive properties |
