Abstract
Novel nano-structured films of V2O5 are prepared by pulsed laser deposition method. Nanoscaled V2O5 ridges lie on SrTiO3 substrate and construct into grid-textured structures. Structural properties of the films have been analyzed by scanning electron microscope, X-ray diffraction and transmission electron microscope. The films have enlarged surface-to-volume ratio due to the ridge-channel structure which makes them applicable to gas sensing. Therefore, gas sensors based on the V2O5 films have been assembled which present reliable sensing properties to gaseous acetone, and ethanol at room temperature. The physical-chemical reactions between adsorbed O2– and testing gases are the possible reason for this property.
