| Abstract: | Poly-vanadium-molybdenum acid H2V12–xMoxO31±y·nH2O (0≤x≤4) xerogel thin films were prepared by sol-gel process. The effects of the content of molybdenum, electrode materials and temperature on the humidity sensing properties of H2V12–xMoxO31± · nH2O were discussed. The results of experimental investigations show that H2V10Mo2O31±y·nH2O (x=2) xerogel thin films have high sensitivity, quick response and little hysteresis as humidity sensors at the conditions of 1 kHz, 20℃ when the thin films are coated on Au electrode. There are a better linear relationship between logarithmic capacitance and relative humidity in total RH range. |
| Keywords: | inorganic non-metallic materials poly-vanadium-molybdenum xerogel thin films humidity sensing properties |
