The humidity sensitive characteristics of the sensor fabricated from 10 mol% Ladoped CeOnanopowders with particle size 17.26 nm synthesized via hydrothermal method were investigated at different frequencies. It was found that the sensor shows high humidity sensitivity, rapid response-recovery characteristics, and narrow hysteresis loop at 100 Hz in the relative humidity range from 11% to 95%. The impedance of the sensor decreases by about five orders of magnitude as relative humidity increases. The maximum humidity hysteresis is about 6% RH, and the response and recovery time is 12 and 13 s, respectively. These results indicate that the nanosized Ladoped CeOpowder has potential application as high-performance humidity sensor. © 2014 Chunjie Wang et al.

Abstract
The humidity sensitive characteristics of the sensor fabricated from 10 mol% Ladoped CeOnanopowders with particle size 17.26 nm synthesized via hydrothermal method were investigated at different frequencies. It was found that the sensor shows high humidity sensitivity, rapid response-recovery characteristics, and narrow hysteresis loop at 100 Hz in the relative humidity range from 11% to 95%. The impedance of the sensor decreases by about five orders of magnitude as relative humidity increases. The maximum humidity hysteresis is about 6% RH, and the response and recovery time is 12 and 13 s, respectively. These results indicate that the nanosized Ladoped CeOpowder has potential application as high-performance humidity sensor. © 2014 Chunjie Wang et al.File | Dimensione | Formato | |
