Vanadium Doped Tungsten Oxide Material - Electrical Physical and Sensing Properties

The electrical physical and sensing (to VOCs and inorganic gases) properties of vanadium doped tungsten oxide in the regions of phase transition temperature were investigated. Vanadium oxide (II) dimerization was observed in the doped material, corresponding to new phase transition. The extreme sens...

Description
Summary:The electrical physical and sensing (to VOCs and inorganic gases) properties of vanadium doped tungsten oxide in the regions of phase transition temperature were investigated. Vanadium oxide (II) dimerization was observed in the doped material, corresponding to new phase transition. The extreme sensitivity and selectivity to chemically active gases and vapors in small concentrations: CO, NOx, NH3 acetone, ethanol near phase transitions temperature was found. Sensor elements were manufactured for the quantitative detection (close to 1 ppm) of alcohol and ammonia.
