| Abstract: | Po ly??v anadium??moly bdenum acid xerog el thin films hav e been fabricated using V2O5 and Mo pow??der s as the precur sors by a sol??g el process. The compound has a layered st ructure. The valency of the Moand V are Mo6+ and V5+ , r espect ively. T he humidity sensing pro pert ies o f the thin films are g ood in therelat ive humidity r ange 11% ~ 95%, the respo nse t ime and the recovery t ime are 6 s and 15 s, the tempera??ture error of the humidity is 0. 5%RH/ ?? . |
