| 摘 要： | 采用共沉淀法制备了Zn2SnO4-LiZnVO4系纳米粉体,考察了液相掺杂LiZnVO4对材料微结构、湿敏性能的影响,分析了材料的复阻抗特性和频率特性。结果表明,适当的LiZnVO4添加量可明显改善Zn2SnO4-LiZnVO4系纳米材料的微结构和感湿特性。采用共沉淀法制备纳米粉体并使LiZnVO4液相掺杂为10%(摩尔分数),可使Zn2SnO4材料具有低湿电阻小、灵敏度适中的湿敏特性,频率特性表明该材料具有较好的频率响应。

| Abstract: | Zn2SnO4-LiZnVO4 system nanometer powders were prepared by co-precipitation. The influence of the amount of liquid-doped LiZnVO4 on the microstructure and humidity-sensitive characteristics of Zn2SnO4 was studied. The composite impendence and the characteristics of frequencies were analyzed. The experimental results show that humidity sensitive and microstructure characteristics of nanometer material can be improved by controlling the amount of liquid-doped LiZnVO4. A humidity sensitive material with lower resistance at lower humidity and with proper humidity sensitivity can be made by liquid-doped x(LiZnVO4)=10% in co-precipitation Zn2SnO4 powders. The characteristics of frequencies show that the material has better respond to frequencies. |
