摘要
在Al2O3衬底上制备了YBa2-xLaxCu3O7-δ(0≤x≤0.15)厚膜,研究了La部分替代Ba对YBa2Cu3O7-δ氧传感器性能的影响。La掺杂显著减小了恢复时间,但灵敏度稍有下降。进一步研究得到了x=0.1样品的电阻随氧分压和温度的变化关系,利用此关系可以来计算某一温度下的环境氧分压。
YBa2-xLaxCu3O7-δ（0≤x≤0.15） thick films on Al2O3 substrate were prepared and the effect of La partial substitution for Ba on the properties of YBa2Cu3O7-δ oxygen sensor was investigated. The re- covery time is remarkably reduced due to La doping, but the sensitivity is also reduced. The relationship of resistance with oxygen partial pressure and temperature for x=0. 1 sample was also obtained, and using the equation one can calculate the oxygen partial pressure at a temperature.
