single-crystal LaF3(5 %CaF2) as the electrolyte and the air with CO as the sensitive electrode.The electro-motive force(EMF) experiments about the sensor is carried out under lower temperature.At given temperature
the relationship between EMF and logarithmic transformation of volume fraction of CO is better linear.The response time of the sensor is shorter than 15 s.It can be seen from the Z-PLOT that single-crystal LaF3(5 %CaF2) has a high ion conductivity.
